[0032] The specific implementation of the present application is described in more detail below in combination with specific embodiments:

[0033] Please refer to Figures 1-3 The optical adjustment device provided in the embodiments of the present application is used for angle adjustment and position adjustment of the optical element 100'. The optical adjustment device includes an optical support 100, an angle adjustment screw 200 and a position adjustment assembly 300. It should be noted that the optical adjustment device provided in the embodiments can be used for angle adjustment and position adjustment of optical elements 100', such as lenses, optical filters, mirrors, etc. Among them, the meaning of angle adjustment in the embodiments is to adjust the inclination angle of the optical element 100' relative to the horizontal plane, and the meaning of position adjustment in the embodiments is to adjust the orientation of the optical element 100'.

[0034] The optical support 100 includes two support structures 110 spaced apart along a first axis and commonly used to support the optical element 100', and a support body 120 used to support the two support structures 110; the angle adjustment screw 200 is connected with the optical element 100', and the angle adjustment screw 200 is used to drive one side of the optical element 100' to move along the first direction relative to the support body 120, so that the optical element 100' can rotate around the first axis; the position adjustment assembly 300 includes a position adjustment shaft 310 connected with the support body 120 and a shaft adjustment assembly 320 used to drive the position adjustment shaft 310 to rotate around a second axis, and the position adjustment shaft 310 can drive the optical support 100 and the optical element 100' to rotate around the second axis under the driving of the shaft adjustment assembly 320.

[0035] It should be noted that when the optical element 100' is supported by the optical support 100, the optical element 100' is located between the two support structures 110, and under the support of the support body 120 and the two support structures 110, the optical element 100' will only have the freedom of rotational movement relative to the first axis. The angle adjusting screw 200 is arranged to extend along the first direction, and by rotating the adjusting nut of the angle adjusting screw 200, the angle adjusting screw 200 can be moved along the first direction relative to the optical support 100, based on which, the angle adjusting screw 200 will drive one side of the optical element 100' to move along the first direction, and at the same time, based on the freedom of the optical element 100', the other side of the optical element 100' will move in the opposite direction, so that the optical element 100' rotates relative to the first axis, so that the inclination angle of the optical element 100' can be quickly and conveniently adjusted, and by controlling the number of rotations of the angle adjusting screw 200, the inclination angle of the optical element 100' can also be accurately controlled. Preferably, the first axis is arranged parallel to the horizontal plane, and the first direction is arranged perpendicular to the first axis, and in this way, the inclination angle of the optical element 100' relative to the horizontal plane can be more conveniently and accurately grasped.

[0036] It should also be noted that the position adjusting shaft 310 is connected with the support body 120, and when the position adjusting shaft 310 rotates around the second axis, the support body 120 will drive the optical element 100' to rotate synchronously with the position adjusting shaft 310. Based on this, by rotating the position adjusting shaft 310 around the second axis through the shaft adjusting assembly 320, the support body 120 and the optical element 100' can be synchronously rotated around the second axis, so that the orientation of the optical element 100' can be adjusted to ensure that the optical element 100' can effectively and accurately receive the light path and produce optical effects on the light path. Preferably, the second axis is arranged perpendicular to the horizontal plane, and in this way, the adjustment of the optical element 100' by the angle adjusting screw 200 and the adjustment of the optical element 100' by the position adjusting assembly 300 can be effectively avoided from affecting each other, so that the adjustment effect of the optical element 100' by the angle adjusting screw 200 and the position adjusting assembly 300 can be maximized.

[0037] The optical adjusting device provided by the embodiment of the present application supports the optical element 100' through the two support structures 110, so that the optical element 100' has only the freedom of rotation around the first axis relative to the optical support 100, and then the angle adjusting screw 200 is adjusted to drive one side of the optical element 100' to move relative to the optical support 100 in the first direction and drive the other side of the optical element 100' to move in the opposite direction, so that the optical element 100' can rotate around the first axis and can be quickly and accurately adjusted to the required inclination angle. The optical adjusting device can also drive the position adjusting shaft 310 to rotate around the second axis through the rotating shaft adjusting assembly 320, so as to drive the optical support 100 and the optical element 100' connected with the position adjusting shaft 310 to rotate around the second axis, thereby quickly and accurately adjusting the optical element 100' to the required position. The optical adjusting device provided by the embodiment of the present application can quickly and accurately adjust the optical element 100' to the required position and inclination angle, has a compact structure, low assembly difficulty of the optical element 100', simple adjustment mode, high adjustment precision, and can conveniently and accurately obtain ideal optical parameters.

[0038] Please refer to Figure 1 、 4 -5, in the embodiment, the position adjusting shaft 310 includes a rotating part 311 extending along the second axis and used for being connected with the support body 120 and a linkage part 312 connected with the rotating part 311 away from the support body 120, and the rotating shaft adjusting assembly 320 includes a position adjusting screw 321 connected with the linkage part 312 and used for driving one end of the linkage part 312 away from the rotating part 311 to move in the second direction, and the linkage part 312 can drive the rotating part 311 to rotate around the second axis under the driving of the position adjusting screw 321. It should be noted that the rotating part 311 extends along the second axis, and when the rotating part 311 rotates around the second axis, the support body 120 and the optical element 100' will rotate around the second axis synchronously. The linkage part 312 is connected with the rotating part 311 away from the support body 120 and extends vertically and outwardly, and based on the arrangement of the linkage part 312, the connection convenience and stability of the position adjusting screw 321 and the position adjusting shaft 310 can be guaranteed and improved, and the rotating precision of the position adjusting shaft 310 can be accurately controlled through the position adjusting screw 321. Specifically, the position adjusting screw 321 can be driven to move in the second direction through the rotation of the adjusting nut of the position adjusting screw 321, and based on this, one side of the linkage part 312 is driven to move in the second direction, so that the linkage part 312 drives the rotating part 311 to rotate around the second axis, thereby quickly, conveniently and accurately adjusting the position of the optical element 100'. The position of the optical element 100' can also be accurately controlled through the control of the rotation number of the position adjusting screw 321.

[0039] Please refer to Figure 1 、 4 -5, in this embodiment, the pivot adjustment assembly 320 further comprises a balance elastic member 322 elastically abutting against the side of the linkage portion 312 away from the position adjustment screw 321. It should be noted that when the position adjustment screw 321 drives the linkage portion 312 to rotate around the second axis, the balance elastic member 322 provided on the side of the linkage portion 312 away from the position adjustment screw 321 will be elastically deformed in the same direction as the movement direction of the position adjustment screw 321, and will generate an elastic force on the linkage portion 312 opposite to the force exerted by the position adjustment screw 321 on the linkage portion 312, so that the linkage portion 312 is always in a state of force balance. Thus, based on the provision of the balance elastic member 322, the stability of the optical element 100' can be effectively guaranteed during the adjustment of the position of the optical element 100' by the position adjustment assembly 300. In this way, not only can the correctness of the observation data be effectively guaranteed, but also the adjustment accuracy and convenience of the position of the optical element 100' can be improved, and the adjustment error value of the position of the optical element 100' can be effectively reduced, and the stability of the optical performance of the optical element 100' during operation can be guaranteed, i.e., the stability of the optical path can be guaranteed.

[0040] Please refer to Figures 1-3 In this embodiment, the support body 120 comprises a support support portion 121 for supporting the two support structures 110 and a support connecting portion 122 for connecting with the position adjustment pivot 310, the support connecting portion 122 is arranged in parallel with the horizontal plane, and the support support portion 121 is arranged intersecting with the support connecting portion 122. It should be noted that by arranging the support connecting portion 122 in parallel with the horizontal plane, not only can the connection convenience and stability between the support connecting portion 122 and the position adjustment pivot 310 be improved, but also the inclination angle between the support support portion 121 and the horizontal plane can be accurately set based on the support connecting portion 122. And by arranging the support support portion 121 at an inclination angle relative to the horizontal plane, not only can the two support structures 110 and the optical element 100' be effectively supported, but also the inclination angle of the optical element 100' relative to the horizontal plane can be referenced, so as to further improve the adjustment accuracy of the inclination angle of the optical element 100' and the adjustment convenience of the optical adjustment device.

[0041] It is to be further explained that the optical element 100' comprises the optical functional part 110' for playing an optical function and the optical connecting part 120' for connecting with the angle adjusting screw 200, the optical connecting part 120' is arranged in parallel with the horizontal plane, and the optical functional part 110' is arranged intersecting the optical connecting part 120'. It is to be explained here that, by arranging the optical connecting part 120' in parallel with the horizontal plane, not only the connection convenience and stability between the optical connecting part 120' and the angle adjusting screw 200 can be improved, but also the inclination angle between the optical functional part 110' and the horizontal plane can be accurately set based on the optical connecting part 120'. And by arranging the optical functional part 110' in a certain angle relative to the horizontal plane, the inclination angle of the optical element 100' can be further guaranteed and improved in adjustment precision by comparing and referring to the support support part 121, and the adjustment convenience of the optical adjusting device can be further improved.

[0042] It is to be explained that Figures 1-3 In the embodiment, the angle value of the included angle between the support support part 121 and the horizontal plane is 45°. It is to be explained here that, in the optical system, the optical element 100' is often used to form an included angle of 45° with the horizontal plane to fold or split the light path. Based on this, on the basis of meeting the inclination angle and position adjustment requirements, the angle value of the included angle between the support support part 121 and the horizontal plane is set to 45° in the embodiment, so as to stably support the two support structures 110 and the optical element 100' by the support support part 121, and use the support support part 121 as the reference for adjusting the inclination angle of the optical element 100', so as to accurately grasp the adjustment of the inclination angle of the optical element 100', and the time required for adjusting the optical element 100' to the required inclination angle can be correspondingly compressed, that is, the adjustment convenience of the optical adjusting device is further improved.

[0043] It is to be explained that Figures 1-2,5, in this embodiment, the optical adjustment device further comprises a stable elastic member 400 elastically abutting between the support support part 121 and the optical element 100'. It should be noted that when the angle adjustment screw 200 drives the optical element 100' to rotate around the first axis, the stable elastic member 400 arranged on the side of the optical element 100' away from the angle adjustment screw 200 will produce an elastic deformation opposite to the movement of the angle adjustment screw 200, and generate an elastic force on the optical element 100' opposite to the force of the angle adjustment screw 200 acting on the optical element 100', so that the optical element 100' is in a state of force balance. Therefore, based on the arrangement of the stable elastic member 400, the stability of the optical element 100' can be effectively guaranteed during the adjustment of the inclination angle of the optical element 100' by the angle adjustment screw 200. In this way, the correctness of the observation data can be effectively guaranteed to improve the adjustment accuracy and convenience of the inclination angle of the optical element 100', effectively reduce the adjustment error value of the inclination angle of the optical element 100', and guarantee the stability of the optical path.

[0044] Please refer to Figures 1-2 ,5, in this embodiment, the distance between the support body 120 and the optical element 100' is 2-4 mm. It should be noted that by setting the distance between the support body 120 and the optical element 100' to 2-4 mm, the fine adjustment range of the inclination angle of the optical element 100' can be limited to compress the adjustment range, thereby improving the adjustment accuracy of the optical element 100' and correspondingly compressing the time required to adjust the optical element 100' to the required inclination angle, thereby improving the adjustment convenience of the optical adjustment device. Preferably, the distance between the support body 120 and the optical element 100' is about 3 mm.

[0045] Please refer to Figure 1 , 4 -5, in this embodiment, the optical adjustment device further comprises a support seat 500 for supporting the angle adjustment screw 200 and the position adjustment assembly 300. It should be noted that the support seat 500 can support and protect the angle adjustment screw 200 and the position adjustment assembly 300 together, and facilitate the assembly convenience of the angle adjustment screw 200 and the position adjustment assembly 300, so that the optical adjustment device has the advantages of simple structure, good use performance and convenient assembly on the basis of guaranteeing the optical adjustment performance of the optical adjustment device.

[0046] Please refer to Figure 1 , 4-5, in the embodiment, the position adjusting assembly 300 further comprises a position adjusting bearing 330 sleeved with the position adjusting rotating shaft 310. It should be noted that the position adjusting bearing 330 is arranged to effectively support the position adjusting rotating shaft 310, avoid the bending deformation of the position adjusting rotating shaft 310 during rotation, and reduce the friction coefficient of the position adjusting rotating shaft 310 during rotation to a certain extent, so as to reduce the abrasion of the position adjusting rotating shaft 310, improve the service life of the position adjusting rotating shaft 310, and guarantee the rotation accuracy of the position adjusting rotating shaft 310, which can further guarantee the position adjusting accuracy of the optical element 100'. Preferably, the position adjusting bearing 330 is in interference fit with the support seat 500 to avoid the deviation of the position adjusting bearing 330 relative to the support seat 500.

[0047] The optical adjusting device provided by the embodiment of the present application supports the optical element 100' through the two support structures 110, so that the optical element 100' has only the freedom of rotation around the first axis relative to the optical support 100. Then, the angle adjusting screw 200 is adjusted to drive one side of the optical element 100' to move relative to the optical support 100 in the first direction, and the other side of the optical element 100' to move in the opposite direction, so that the optical element 100' can rotate around the first axis and be quickly and accurately adjusted to the required inclination angle. The optical adjusting device also drives the position adjusting rotating shaft 310 to rotate around the second axis through the rotating shaft adjusting assembly 320, so as to drive the optical support 100 and the optical element 100' connected with the position adjusting rotating shaft 310 to rotate around the second axis, thereby quickly and accurately adjusting the optical element 100' to the required position. The optical adjusting device provided by the embodiment of the present application can quickly and accurately adjust the optical element 100' to the required position and inclination angle, has a compact structure, low assembly difficulty of the optical element 100', simple adjustment mode, high adjustment accuracy, and can conveniently and accurately obtain the ideal optical parameters.
