Technical Field

[0002] Optical systems are used to process light beams, and the processing may include shaping, deflecting, focusing, collimating, etc. of the light beams to adjust the optical characteristics of the light beams so as to meet different application requirements.

[0003] A laser optical system is a typical optical system, which generally includes a plurality of optical components such as lenses and mirrors. These optical components are installed on the base of the laser optical system to process the laser beam when the laser beam passes through the optical components. In a laser optical system, it is important to align the optical components with the optical axis of the laser beam so that the laser beam can pass through the optical components in the correct orientation. In existing laser optical systems, when an optical component is installed on the base of the laser optical system (for example, when the optical component is installed for the first time or reinstalled due to maintenance or replacement), the operator usually holds the optical component and moves it relative to the base to adjust the position of the optical component on the base so as to align it with the optical axis of the laser beam. However, this method is time-consuming and laborious, and the installation accuracy is low, making it difficult to ensure the precise alignment of the optical component with the optical axis of the laser beam.

[0044] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that these embodiments do not impose any limitations on the present application. In addition, the features in the embodiments of the present application can be combined with each other without conflict.

[0045] Figures 1A to 1C Schematically shows an exemplary optical system 1. As an example, the optical system 1 can be a laser optical system, which is configured to process a laser beam (not shown). The processing can include shaping, deflecting, focusing, collimating, etc. of the laser beam to adjust the optical characteristics of the laser beam to meet different application requirements. The laser beam is generated by a laser light source and has an optical axis OA (the optical axis is schematically represented by a dash-dot line at a single point in Figures 1A to 1C ). The optical axis refers to the center line of the light beam, and the light beam rotates around the optical axis without changing its optical characteristics. The adjusting tool according to the present application will be described below by taking the optical system 1 as an example of a laser optical system. It should be understood that the adjusting tool according to the present application is not limited in terms of application, and it can also be used in other optical systems.

[0046] As shown in Figure 1A , the optical system 1 can include a base 3 and an optical component 5 to be mounted on the base 3. The base 3 is configured to mount and arrange the optical component 5 so that the optical component 5 can be in a position fixed relative to the optical axis OA in the optical system 1, so that the optical component 5 can process the laser beam. The position of the optical axis OA relative to the base 3 is fixed.

[0047] Figure 1DA configuration of an exemplary optical component 5 is shown in detail. As an example, the optical component 5 may be a lens component. The optical component 5 may include an optical element 6 (e.g., a lens element) and a bracket 7. The bracket 7 is configured to support and hold the optical element 6 and to be mounted on a base surface 3a of the base 3. The lens element may be any suitable type of lens, e.g., a convex lens or a concave lens.

[0048] As Figure 1B and Figure 1C shown, the optical component 5 may be mounted on the base surface 3a of the base 3 and arranged along the optical axis OA of the laser beam, so as to process the laser beam. When mounting the optical component 5 onto the base 3, it is necessary to align the optical component 5 with the optical axis OA. In this example, it is necessary to align the lens center of the lens element with the optical axis OA. As will be specifically described below, the adjustment tool according to the present application is configured to be able to carry the optical component 5 and adjust the position of the optical component 5 on the base 3 during the mounting of the optical component 5 onto the base 3, so as to achieve precise alignment of the optical component 5 with the optical axis OA.

[0049] For clarity and conciseness of description, a first direction Z-Z, a second direction X-X, and a third direction Y-Y are defined in Figures 1A to 8B . The first direction Z-Z, the second direction X-X, and the third direction Y-Y are perpendicular to each other. The first direction Z-Z is parallel to the optical axis OL and parallel to the base surface 3a of the base 3. The second direction X-X is perpendicular to the first direction Z-Z and the optical axis OL and parallel to the base surface 3a of the base 3. The third direction Y-Y is perpendicular to the first direction Z-Z and the optical axis OL and perpendicular to the base surface 3a of the base 3.

[0050] Figures 2A to 8B A configuration of an adjustment tool 10 according to some embodiments of the present application is shown in detail. As Figure 2A and Figure 2B shown, the adjustment tool 10 is configured to be able to carry the optical component 5 and adjust the position of the optical component 5 on the base 3 during the mounting of the optical component 5 onto the base 3, so as to align the optical component 5 with the optical axis OA. The adjustment tool 10 may be fixed in place relative to the base 3. For example, as Figure 2A shown, the adjustment tool 10 may be fixed on the base 3. The adjustment tool 10 may be configured to adjust the position of the optical component 5 relative to the base 3 in the first direction Z-Z, the second direction X-X, and the third direction Y-Y.

[0051] Specifically, the adjustment tool 10 may include a first adjustment mechanism 100, a second adjustment mechanism 200, and a third adjustment mechanism 300 to adjust the position of the optical component 5 relative to the base 3 in the first direction Z-Z, the second direction X-X, and the third direction Y-Y, respectively, so as to accurately align the optical component 5 with the optical axis OA. As Figures 2A to 3 shown, the first adjustment mechanism 100 includes a first slider 110 configured to be translatable relative to the base 3 along a first direction Z-Z parallel to the optical axis OL. The second adjustment mechanism 200 is connected to the first slider 110 to translate together with the first slider 110. The second adjustment mechanism 200 includes a second slider 210 configured to be translatable relative to the first slider 110 along a second direction X-X perpendicular to the first direction Z-Z. That is, the second slider 210 can translate along the first direction Z-Z with the first slider 110 and can translate independently of the first slider 110 along the second direction X-X. The third adjustment mechanism 300 is connected to the second slider 210 to translate together with the second slider 210. The third adjustment mechanism 300 includes a third slider 310 configured to be translatable relative to the second slider 210 along a third direction Y-Y perpendicular to the first direction Z-Z and the second direction X-X. That is, the third slider 310 can translate along the first direction Z-Z with the first slider 110, can translate along the second direction X-X with the second slider 210, and can translate independently of the first slider 110 and the second slider 210 along the third direction Y-Y. The third slider 310 is configured to carry the optical component 5 and translate together.

[0052] With this configuration, the adjustment tool 10 can carry the optical component 5 during the installation of the optical component 5 on the base 3 and can accurately adjust the position of the optical component 5 on the base 3 in three mutually perpendicular directions to accurately align the optical component 5 with the optical axis OA. The adjustment tool 10 has three degrees of freedom. Compared with adjusting the optical component 5 by hand held by an operator, adjusting the position of the optical component 5 on the base 3 by using the adjustment tool 10 can improve the efficiency and accuracy.

[0053] In some embodiments, as Figures 2A to 3 shown, the first adjustment mechanism 100 may include a guide rail 120. The guide rail 120 is configured to be fixedly arranged relative to the base 3 of the optical system 1. Two guide rails 120 are shown in the figure. Each guide rail 120 may be elongated and arranged parallel to the first direction Z-Z. The two guide rails 120 may be spaced apart from each other in the second direction X-X.

[0054] As Figures 3 to 4BAs shown, the first slider 110 may include a first platform portion 111, which may have a plate-like shape and include a first surface (top surface) 111a and a second surface (bottom surface) 111b that are opposite to each other in the third direction Y-Y. As Figure 4A shown, the first platform portion 111 may further include a support portion 112 protruding from the second surface 111b along the third direction Y-Y. Two support portions 112 are shown in the figure. Each support portion 112 includes a chute 112a extending through the support portion 112 along the first direction Z-Z. As Figure 2A and Figure 2B shown, each support portion 112 is configured to be mounted on a corresponding one of the two guide rails 120 such that the first slider 110 is slidably mounted on the guide rail 120. The chute 112a of each support portion 112 matches the corresponding guide rail 120 in shape to allow the support portion 112 to translate along the first direction Z-Z on the corresponding guide rail 120 and to restrict the support portion 112 from moving relative to the corresponding guide rail 120 along the second direction X-X and the third direction Y-Y. In the present application, movement may include translation and rolling. In this way, the first slider 110 can translate along the first direction Z-Z parallel to the optical axis OL relative to the base 3 on the guide rail 120, so that the position of the optical component 5 on the base 3 along the first direction Z-Z can be adjusted.

[0055] As Figures 1A to 1C and Figure 2A shown, the base 3 of the optical system 1 may include a first support portion 3b and a second support portion 3c extending from the base surface 3a along the third direction Y-Y. The first support portion 3b and the second support portion 3c may be respectively disposed at two opposite ends of the base 3 in the first direction Z-Z. The first support portion 3b and the second support portion 3c may respectively define apertures 3d and 3e to allow the laser beam to pass through.

[0056] In some embodiments, as Figure 2A 、 Figure 2B and Figure 3As shown, the first adjustment mechanism 100 may include a mounting base 130 configured to be fixed to the base 3 of the optical system 1. Specifically, the mounting base 130 may have a plate-like shape and include a first surface (top surface) 131 and a second surface (bottom surface) 132 that are opposite to each other in the third direction Y-Y. The mounting base 130 is fixed to the first support portion 3b and the second support portion 3c of the base 3 of the optical system 1. The first support portion 3b and the second support portion 3c support the second surface 132 of the mounting base 130 at opposite ends of the mounting base 130 in the first direction Z-Z, respectively, thereby holding the mounting base 130 above the base surface 3a of the base 3. The guide rail 120 is fixedly provided on the first surface 131 of the mounting base 130. Providing the mounting base 130 and arranging the guide rail 120 on the mounting base 130 can improve the integration degree of the adjustment tool 10 and facilitate the deployment and removal of the adjustment tool 10.

[0057] In some embodiments, as Figure 2A , Figure 2B and Figure 3 shown, the mounting base 130 may include an opening 133 that extends through the mounting base 130 along the third direction Y-Y and extends along the first direction Z-Z. As will be specifically described below, the carrying arm 320 of the third adjustment mechanism 300 can extend from one side of the first surface 131 of the mounting base 130 through the opening 133 to the other side of the second surface 132. The carrying arm 320 can be used to carry the optical component 5 to move relative to the base 3 above the base surface 3a of the base 3.

[0058] In some embodiments, as Figures 4B to 5C shown, the second adjustment mechanism 200 may include a first base body 230 that is fixed to the first slider 110. Therefore, the first base body 230 can translate along the first direction Z-Z together with the first slider 110. As Figures 4B to 4D shown, the first platform portion 111 of the first slider 110 may include a support portion 114 that protrudes along the third direction Y-Y from the first surface 111a. As Figure 4C shown, the first base body 230 of the second adjustment mechanism 200 is fixed to the support portion 114 of the first platform portion 111 of the first slider 110. It should be understood that the present application is not limited thereto. In other partial embodiments, the first base body 230 may be fixed to the first slider 110 by any suitable method or mechanism, or the first base body 230 may be integrally formed with the first slider 110.

[0059] The second slider 210 of the second adjusting mechanism 200 is slidably mounted to the first base body 230. Specifically, the second slider 210 is configured to be mounted on the first base body 230 so as to translate along the first direction Z-Z together with the first base body 230 and the first slider 110 (which are fixed to each other as described above), and the second slider 210 is configured to be able to translate relative to the first base body 230 and the first slider 110 along the second direction X-X. With this configuration, the second slider 210 can translate along the first direction Z-Z with the first slider 110, and can itself translate along the second direction X-X independently of the first base body 230 and the first slider 110.

[0060] In some embodiments, as Figures 4C to 4D , Figures 5A to 5C and Figures 8A to 8B shown, the first base body 230 includes a first sliding groove 250 extending along the second direction X-X. The second slider 210 includes a first protrusion 211. The first protrusion 211 may be fixed to the second slider 210 or integrally formed with the second slider 210. The first protrusion 211 includes a first threaded hole 211a extending through the first protrusion 211 along the second direction X-X. The first threaded hole 211a may have internal threads. As Figure 8A and Figure 8B best shown, when the second slider 210 is slidably mounted to the first base body 230, the first protrusion 211 is received in the first sliding groove 250 and can slide in the first sliding groove 250 along the second direction X-X. The second adjusting mechanism 200 may include an adjusting assembly 260 configured to adjust the position of the second slider 210 relative to the first base body 230 in the second direction X-X. The adjusting assembly 260 may include a first threaded rod 261. As Figure 8A shown, the first threaded rod 261 has a first central axis CA1. The first threaded rod 261 is mounted in the first sliding groove 250 in a manner capable of rotating about the first central axis CA1, wherein the first central axis CA1 is oriented parallel to the second direction X-X, the first threaded rod 261 extends along the second direction X-X, and passes through the first threaded hole 211a of the first protrusion 211 and is in threaded connection with the first threaded hole 211a. Since the first threaded rod 261 is in threaded connection with the first threaded hole 211a, the first threaded rod 261 can hold the first protrusion 211, thereby holding the second slider 210 to the first base body 230. When the first threaded rod 261 is rotated about the first central axis CA1, the first protrusion 211 is driven to translate in the first sliding groove 250 along the second direction X-X, thereby causing the second slider 210 to translate relative to the first base body 230 along the second direction X-X.

[0061] Exemplarily, Figure 8AIt shows that the first protrusion 211 of the second slider 210 is in the initial position, in which the first protrusion 211 of the second slider 210 can be located on the middle section of the first threaded rod 261 and in the middle section of the first chute 250. When the first threaded rod 261 is rotated along the first rotation direction (e.g., clockwise), the first protrusion 211 is driven to translate on the first threaded rod 261 towards one end of the first threaded rod 261, and when the first threaded rod 261 is rotated along the second rotation direction opposite to the first rotation direction (e.g., counterclockwise), the first protrusion 211 is driven to translate on the first threaded rod 261 towards the other end of the first threaded rod 261.

[0062] In some embodiments, as Figure 4C , Figures 5A to 5C and Figures 8A to 8B shown, the first base 230 includes a first surface 231 and a second protrusion 232 that protrudes from the first surface 231 and extends along the second direction X-X. The second protrusion 232 includes a first bottom 232a connected to the first surface 231 and a first top 232b opposite to the first bottom 232a. The first top 232b may include a top surface 232c. The top surface 232c and the first surface 231 may be parallel to each other. For example, as shown in the figure, both the top surface 232c and the first surface 231 may extend perpendicular to the first direction Z-Z. The top surface 232c and the first surface 231 face the same direction, e.g., facing the first direction Z-Z. The first chute 250 may be recessed into the first base 230 from the top surface 232c of the first top 232b. The first chute 250 may divide the second protrusion 232 into two sub-segments spaced apart from each other.

[0063] Please refer to Figure 4D and Figures 8A to 8B , the second slider 210 includes a second surface 212 and a second chute 213 that is recessed into the second slider 210 from the second surface 212 and extends along the second direction X-X. The second chute 213 may include a bottom surface 213a. The first protrusion 211 protrudes from the bottom surface 213a of the second chute 213. The second chute 213 may extend through the second slider 210 along the second direction X-X.

[0064] As Figure 8A and Figure 8BAs best shown, when the second slider 210 is slidably mounted to the first base 230, the first surface 231 faces the second surface 212, the second protrusion 232 is received in the second chute 213, and the top surface 232c of the first top 232b faces the bottom surface 213a of the second chute 213. The second protrusion 232 and the second chute 213 are shaped to match each other to allow the second protrusion 232 to translate along the second direction X-X in the second chute 213 and to restrict the second protrusion 232 from moving relative to the second chute 213 along the first direction Z-Z and the third direction Y-Y. In the present application, movement may include translation and rolling. In this way, the second protrusion 232 and the second chute 213 can cooperate with each other to slidably hold the second slider 210 on the first base 230. The second protrusion 232 and the second chute 213 can cooperate with each other to guide the second slider 210 to translate along the second direction X-X relative to the first base 230 and to restrict the second slider 210 from moving relative to the first base 230 along the first direction Z-Z and the third direction Y-Y. This configuration can improve the reliability of the second adjustment mechanism 200.

[0065] In some embodiments, as Figure 5B and Figure 8B shown, the cross-section of the second protrusion 232 perpendicular to the second direction X-X has an outer contour in the shape of a dovetail. The first bottom 232a has a first width W1 in the width direction perpendicular to the second direction X-X, and the first top 232b has a second width W2 in the width direction. The first width W1 is less than the second width W2. The second protrusion 232 and the second chute 213 are shaped to match each other, so the cross-section of the second chute 213 perpendicular to the second direction X-X has an inner contour in the shape of a dovetail. This shape of the second protrusion 232 and the second chute 213 can provide sufficient holding force therebetween to slidably hold the second slider 210 on the first base 230. It should be understood that the present application is not limited thereto, and in other embodiments, the second protrusion 232 and the second chute 213 may have any other suitable cross-sectional profiles to achieve cooperation with each other.

[0066] In some embodiments, as Figure 5A 、 Figure 5C and Figure 8AAs shown, the first chute 250 can extend through the first base body 230 along the second direction X-X, and includes a first end 251 and a second end 252 that are opposite to each other in the second direction X-X. The adjusting assembly 260 of the second adjusting mechanism 200 can include a first support washer 271 having a first aperture 271a and a second support washer 272 having a second aperture 272a. The first support washer 271 and the second support washer 272 are respectively disposed at the first end 251 and the second end 252, and the first aperture 271a and the second aperture 272a are aligned with each other in the second direction X-X. The first base body 230 includes a first circular receiving portion 251a that expands from the first chute 250 into the first base body 230 at the first end 251, and a second circular receiving portion 252a that expands from the first chute 250 into the first base body 230 at the second end 252. The first support washer 271 and the second support washer 272 are respectively disposed in the first circular receiving portion 251a and the second circular receiving portion 252a. The first threaded rod 261 extends from the first end 251 of the first chute 250 along the second direction X-X through the first aperture 271a of the first support washer 271 and the second aperture 272a of the second support washer 272 to the second end 252 of the first chute 250, and is supported by the first support washer 271 and the second support washer 272 in a manner capable of rotating about the first central axis CA1. The first support washer 271 and the second support washer 272 can be flat washers.

[0067] In one of these embodiments, the adjusting assembly 260 of the second adjusting mechanism 200 can include a third washer 273 and a fourth washer 274. The third washer 273 and the fourth washer 274 can be lock washers. The third washer 273 can be disposed between one end of the first threaded rod 261 and the first support washer 271, and the fourth washer 274 can be disposed between the other end of the first threaded rod 261 and the second support washer 272, so as to help reliably hold the first support washer 271 and the second support washer 272 in the first circular receiving portion 251a and the second circular receiving portion 252a. It should be understood that the present application is not limited thereto. In other partial embodiments, the first threaded rod 261 can be supported by any suitable mechanism in a manner capable of rotating about the first central axis CA1. For example, bearings can be respectively disposed at the first end 251 and the second end 252 of the first chute 250 to support the first threaded rod 261.

[0068] In some embodiments, as Figure 4C , Figure 5A , Figure 5C and Figure 8AAs shown, the adjusting assembly 260 of the second adjusting mechanism 200 may include a first knob 255. The first knob 255 is disposed at one end of the first threaded rod 261 and, when rotated, causes the first threaded rod 261 to rotate about the first central axis CA1. For example, as shown, the first knob 255 may be formed separately from the first threaded rod 261 and connected to one end of the first threaded rod 261. It should be understood that the present application is not limited thereto. In other partial embodiments, the first knob 255 may be integrally formed with the first threaded rod 261.

[0069] The first knob 255 enables the user to precisely adjust the position of the second slider 210 relative to the first base 230 in the second direction X-X. When the first knob 255 is rotated one full turn (i.e., 360 degrees), the second slider 210 may translate a predetermined distance relative to the first base 230 in the second direction X-X, which predetermined distance may be, for example, 1 cm, 2 cm, or a greater or smaller distance. For example, when the first knob 255 is rotated in the first rotational direction (e.g., clockwise), the first threaded rod 261 is also rotated in the first rotational direction, and the first protrusion 211 is driven to translate on the first threaded rod 261 towards one end of the first threaded rod 261, thereby driving the second slider 210 to translate relative to the first base 230 in the second direction X-X. When the first knob 255 is rotated in a second rotational direction opposite to the first rotational direction (e.g., counterclockwise), the first threaded rod 261 is also rotated in the second rotational direction, and the first protrusion 211 is driven to translate on the first threaded rod 261 towards the other end of the first threaded rod 261, thereby driving the second slider 210 to translate relative to the first base 230 in the second direction X-X.

[0070] As Figures 2A to 3 、 Figures 6A to 6B and Figures 8A to 8BAs shown, the third slider 310 is slidably mounted to the second slider 210. Specifically, the third slider 310 is configured to be mounted on the second slider 210 to translate along the second direction X-X together with the second slider 210, and when the second slider 210 translates along the first direction Z-Z together with the first base 230 and the first slider 110, the third slider 310 can translate along the first direction Z-Z together with them. In addition, the third slider 310 can translate relative to the second slider 210 along the third direction Y-Y. With this configuration, the third slider 310 can translate along the first direction Z-Z with the first slider 110, can translate along the second direction X-X with the second slider 210, and can translate independently of the first slider 110 and the second slider 210 along the third direction Y-Y. The sliding fit manner between the third slider 310 and the second slider 210 can be similar to the sliding fit manner between the second slider 210 and the first base 230.

[0071] In some embodiments, as Figures 6A to 6B and Figures 8A to 8B shown, the second slider 210 includes a third chute 280 extending along the third direction Y-Y. The third slider 310 includes a third protrusion 311. The third protrusion 311 can be fixed to the third slider 310 or integrally formed with the third slider 310. The third protrusion 311 includes a second threaded hole 311a extending through the third protrusion 311 along the third direction Y-Y. The second threaded hole 311a can have internal threads. As Figure 8A and Figure 8B best shown, when the third slider 310 is slidably mounted to the second slider 210, the third protrusion 311 is received in the third chute 280 and can slide in the third chute 280 along the third direction Y-Y. The third adjustment mechanism 300 can include an adjustment assembly 360 configured to adjust the position of the third slider 310 relative to the second slider 210 in the third direction Y-Y. The adjustment assembly 360 can include a second threaded rod 361. As Figure 8BAs shown, the second threaded rod 361 has a second central axis CA2. The second threaded rod 361 is mounted in the third chute 280 in a manner capable of rotating about the second central axis CA2, wherein the second central axis CA2 is oriented parallel to the third direction Y-Y, the second threaded rod 361 extends along the third direction Y-Y, and passes through the second threaded hole 311a of the third protrusion 311 and is in threaded connection with the second threaded hole 311a. Since the second threaded rod 361 is in threaded connection with the second threaded hole 311a, the second threaded rod 361 can hold the third protrusion 311, thereby holding the third slider 310 to the second slider 210. When the second threaded rod 361 is rotated about the second central axis CA2, the third protrusion 311 is driven to translate along the third direction Y-Y in the third chute 280, thereby causing the third slider 310 to translate relative to the second slider 210 along the third direction Y-Y.

[0072] Exemplarily, as Figure 8B shown, the third protrusion 311 of the third slider 310 is in an initial position, in which the third protrusion 311 of the third slider 310 can be located on the middle section of the second threaded rod 361 and in the middle section of the third chute 280. When the second threaded rod 361 is rotated along the first rotation direction (e.g., clockwise direction), the third protrusion 311 is driven to translate on the second threaded rod 361 towards one end of the second threaded rod 361, and when the second threaded rod 361 is rotated along the second rotation direction opposite to the first rotation direction (e.g., counterclockwise direction), the third protrusion 311 is driven to translate on the second threaded rod 361 towards the other end of the second threaded rod 361.

[0073] In some embodiments, as Figure 6A 、 Figure 8A and Figure 8B shown, the second slider 210 includes a third surface 215 and a fourth protrusion 216 protruding from the third surface 215 and extending along the third direction Y-Y. The fourth protrusion 216 includes a second bottom 216a connected to the third surface 215 and a second top 216b opposite to the second bottom 216a. The second top 216b may include a top surface 216c. The top surface 216c and the third surface 215 may be parallel to each other. For example, as shown, both the top surface 216c and the third surface 215 may extend perpendicular to the first direction Z-Z. The top surface 216c and the third surface 215 face the same direction, e.g., face the first direction Z-Z. The third chute 280 may be recessed into the second slider 210 from the top surface 216c of the second top 216b. The third chute 280 may divide the fourth protrusion 216 into two sub-segments spaced apart from each other.

[0074] AsFigure 6B , Figure 8A and Figure 8B As shown in Figure 6B , Figure 8A and Figure 8B , the third slider 310 includes a fourth surface 313, and a fourth chute 315 that is recessed from the fourth surface 313 into the third slider 310 and extends along the third direction Y-Y. The fourth chute 315 may include a bottom surface 315a. The third protrusion 311 protrudes from the bottom surface 315a of the fourth chute 315. The fourth chute 315 may extend through the third slider 310 along the third direction Y-Y.

[0075] As Figure 8A and Figure 8B best shown in Figure 8A and Figure 8B , when the third slider 310 is slidably mounted to the second slider 210, the third surface 215 faces the fourth surface 313, the fourth protrusion 216 is received in the fourth chute 315, and the top surface 216c of the second top 216b faces the bottom surface 315a of the fourth chute 315. The fourth protrusion 216 and the fourth chute 315 are shaped to match each other to allow the fourth protrusion 216 to translate along the third direction Y-Y in the fourth chute 315 and to restrict the fourth protrusion 216 from moving relative to the fourth chute 315 along the first direction Z-Z and the second direction X-X. In this application, movement may include translation and rolling. In this way, the fourth protrusion 216 and the fourth chute 315 can cooperate with each other to slidably hold the third slider 310 on the second slider 210. The fourth protrusion 216 and the fourth chute 315 can cooperate with each other to guide the third slider 310 to translate along the third direction Y-Y relative to the second slider 210 and to restrict the third slider 310 from moving relative to the second slider 210 along the first direction Z-Z and the second direction X-X. This configuration can improve the reliability of the third adjustment mechanism 300.

[0076] In some embodiments, as Figure 6A and Figure 8A shown, the cross-section of the fourth protrusion 216 perpendicular to the third direction Y-Y has an outer contour with a dovetail shape. The second bottom 216a has a third width (not labeled) in the width direction perpendicular to the third direction Y-Y, and the second top 216b has a fourth width (not labeled) in the width direction, where the third width is less than the fourth width. The fourth protrusion 216 and the fourth chute 315 are shaped to match each other, so the cross-section of the fourth chute 315 perpendicular to the third direction Y-Y has an inner contour with a dovetail shape. This shape of the fourth protrusion 216 and the fourth chute 315 can provide sufficient holding force therebetween to slidably hold the third slider 310 on the second slider 210. It should be understood that this application is not limited thereto, and in other partial embodiments, the fourth protrusion 216 and the fourth chute 315 may have any other suitable cross-sectional profiles to achieve cooperation with each other.

[0077] In some embodiments, the second threaded rod 361 can be supported in a manner similar to that of the first threaded rod 261. As Figure 6A and Figure 8B shown, the third chute 280 extends through the second slider 210 along the third direction Y-Y, and includes a third end 281 and a fourth end 282 that are opposite to each other in the third direction Y-Y. The adjusting assembly 360 of the third adjusting mechanism 300 can include a third support washer 371 having a third orifice 371a and a fourth support washer 372 having a fourth orifice 372a. The third support washer 371 and the fourth support washer 372 are respectively disposed at the third end 281 and the fourth end 282, and the third orifice 371a and the fourth orifice 372a are aligned with each other in the third direction Y-Y. Exemplarily, the third support washer 371 and the fourth support washer 372 can be respectively disposed in circular receiving portions similar to the circular receiving portions 251a and 252a described above. The second threaded rod 361 extends from the third end 281 of the third chute 280 along the third direction Y-Y through the third orifice 371a and the fourth orifice 372a to the fourth end 282 of the third chute 280, and is supported by the third support washer 371 and the fourth support washer 372 in a manner capable of rotating about the second central axis CA2. The third support washer 371 and the fourth support washer 372 can be flat washers. In one of these embodiments, the adjusting assembly 360 of the third adjusting mechanism 300 can include a lock washer (not shown) to help reliably hold the first support washer 271 and the second support washer 272 at the third end 281 and the fourth end 282. It should be understood that the present application is not limited thereto. In other partial embodiments, the second threaded rod 361 can be supported by any suitable mechanism in a manner capable of rotating about the second central axis CA2. For example, bearings can be respectively disposed at the third end 281 and the fourth end 282 of the third chute 280 to support the second threaded rod 361.

[0078] In some embodiments, as Figure 6A 、 Figure 6B and Figure 8B shown, the third adjusting mechanism 300 can include a second knob 355. The second knob 355 is disposed at one end of the second threaded rod 361, and causes the second threaded rod 361 to rotate about the second central axis CA2 when rotated. For example, as shown in the figure, the second knob 355 can be formed separately from the second threaded rod 361 and connected to one end of the second threaded rod 361. It should be understood that the present application is not limited thereto. In other partial embodiments, the second knob 355 can be integrally formed with the second threaded rod 361.

[0079] The second knob 355 can allow the user to precisely adjust the position of the third slider 310 relative to the second slider 210 in the third direction Y-Y. When the second knob 355 is rotated one full turn (i.e., 360 degrees), the third slider 310 can translate a predetermined distance relative to the second slider 210 in the third direction Y-Y. The predetermined distance can be, for example, 1 cm, 2 cm, or a larger or smaller distance. For example, when the second knob 355 is rotated in the first rotation direction (e.g., clockwise), the second threaded rod 361 is also rotated in the first rotation direction, and the third protrusion 311 is driven to translate on the second threaded rod 361 towards one end of the second threaded rod 361, thereby driving the third slider 310 to translate relative to the second slider 210 in the third direction Y-Y. When the second knob 355 is rotated in the second rotation direction opposite to the first rotation direction (e.g., counterclockwise), the second threaded rod 361 is also rotated in the second rotation direction, and the third protrusion 311 is driven to translate on the second threaded rod 361 towards the other end of the second threaded rod 361, thereby driving the third slider 310 to translate relative to the second slider 210 in the third direction Y-Y.

[0080] In some embodiments, as Figure 6A shown, both the second surface 212 and the third surface 215 of the second slider 210 can extend perpendicular to the first direction Z-Z and can be two surfaces of the second slider 210 that are opposite to each other in the first direction Z-Z. The second chute 213 is recessed into the second slider 210 from the second surface 212 along the first direction Z-Z, and the third chute 280 is recessed into the second slider 210 from the top surface 216c of the second top 216b along the first direction Z-Z. It should be understood that this application is not limited thereto, and in other partial embodiments, the second surface 212 and the third surface 215 of the second slider 210 can be any suitable surfaces of the second slider 210.

[0081] The third slider 310 is configured to carry the optical component 5 and translate together. In some embodiments, as Figures 6A to 7B shown, the third adjustment mechanism 300 can include a carrying arm 320 configured to carry the optical component 5. The carrying arm 320 can extend from one side of the first surface 131 of the mounting base 130 through the opening 133 to the other side of the second surface 132. The carrying arm 320 translates together with the third slider 310. For example, as shown in the figure, the carrying arm 320 can be formed separately from the third slider 310 and fixed to the third slider 310. It should be understood that this application is not limited thereto. In other partial embodiments, the carrying arm 320 can be integrally formed with the third slider 310.

[0082] Please return to reference Figures 1A to 1D, the bracket 7 of the optical component 5 may include a third flat surface 7a and a fourth flat surface 7b. For example, the third flat surface 7a may be the top surface of the bracket 7, and the fourth flat surface 7b may be the rear surface of the bracket 7. The third flat surface 7a and the fourth flat surface 7b extend perpendicular to each other and intersect at a corner 7c. As Figure 1C best shown, when the optical component 5 is set in place on the base 3 of the optical system 1, the third flat surface 7a is oriented perpendicular to the third direction Y-Y, and the fourth flat surface 7b is oriented perpendicular to the first direction Z-Z.

[0083] In some embodiments, as Figure 7A , Figure 7B and Figure 8B shown, the carrier arm 320 may include a platform portion 321. The platform portion 321 includes a first flat surface 321a and a protruding portion 322 that protrudes from the first flat surface 321a. The protruding portion 322 includes a second flat surface 322a. The first flat surface 321a and the second flat surface 322a extend perpendicular to each other and intersect at a corner 323. When the adjustment tool 10 is set in place relative to the base 3 of the optical system 1, the first flat surface 321a is oriented perpendicular to the third direction Y-Y, and the second flat surface 322a is oriented perpendicular to the first direction Z-Z. The platform portion 321 of the carrier arm 320 is configured to receive the bracket 7 of the optical component 5 such that the third flat surface 7a and the fourth flat surface 7b of the bracket 7 of the optical component 5 are respectively engaged with the first flat surface 321a and the second flat surface 322a of the platform portion 321. With this configuration, when the adjustment tool 10 is set in place relative to the base 3 of the optical system 1 and the optical component 5 is carried by the carrier arm 320 of the third adjustment mechanism 300 of the adjustment tool 10, the bracket 7 of the optical component 5 can be carried by the carrier arm 320 in a predetermined orientation (e.g., an orientation in which the fourth flat surface 7b is perpendicular to the first direction Z-Z and perpendicular to the optical axis OA), thereby achieving precise orientation of the bracket 7. In this case, there is no need to further adjust the angles of the bracket 7 relative to the base 3 about an axis parallel to the second direction X-X and about an axis parallel to the third direction Y-Y. This enables rapid and precise orientation of the optical component 5.

[0084] In some embodiments, the carrier arm 320 may include a quick-release structure configured to allow for quick holding and releasing of the optical component 5. With this configuration, the convenience of carrying and releasing the optical component 5 by the carrier arm 320 can be improved, thereby enhancing the efficiency of the adjustment operation.

[0085] In one of these embodiments, at least a portion of the carrier arm 320 (e.g., the platform portion 321) may be made of a magnetic material, and / or the carrier arm 320 may have a magnet to hold the optical component 5 by magnetic attraction. For example, at least a portion of the bracket 7 of the optical component 5 may be supported by a metallic material or a magnetic material, or may have a magnet, enabling the carrier arm 320 to hold it by magnetic attraction. Configuring the carrier arm 320 to be able to hold the optical component 5 by magnetic attraction can enable the carrier arm 320 to adapt to the brackets 7 of various optical components 5, thereby improving the adaptability of the adjustment tool 10.

[0086] The process of mounting the optical component 5 onto the base 3 using the adjustment tool 10 will be described below with reference to FIG. 2.

[0087] First, as Figure 2A shown, the adjustment tool 10 can be fixed to the base 3. Specifically, the mounting seat 130 of the first adjustment mechanism 100 can be fixed to the base 3 of the optical system 1. In this way, the adjustment tool 10 can be mounted onto the base 3.

[0088] Subsequently, as Figure 2A shown, the optical component 5 can be mounted onto the carrier arm 320 of the third adjustment mechanism 300. The optical component 5 is carried by the carrier arm 320.

[0089] The first adjustment mechanism 100 can be adjusted to adjust the position of the optical component 5 relative to the base 3 in the first direction Z-Z. Specifically, the first slider 110 can be slid on the guide rail 120 to adjust the position of the first slider 110 relative to the base 3 in the first direction Z-Z, thereby adjusting the position of the optical component 5 relative to the base 3 in the first direction Z-Z.

[0090] The second adjustment mechanism 200 can be adjusted to adjust the position of the optical component 5 relative to the base 3 in the second direction X-X.
