Description
Technical Field
[0001] This invention relates to the field of optical axis adjustment technology, specifically to an optical axis adjustment device for a microscope optical system. Background Technology
[0002] The optical axis is the axis of symmetry of an optical system. It refers to the straight line where the center line of the beam or the curvature centers of the surfaces in the system are collinear. When using a lens, it is necessary for the optical axis to be perpendicular to the mechanical reference, which is a necessary condition for microscopic imaging. Therefore, it is necessary to ensure that the optical axis is not tilted during installation.
[0003] In the current technology, when detecting and adjusting the optical axis tilt, the installation reference is often adjusted to make the optical axis reach the required state. However, this does not take into account the possibility that the optical axis tilt is caused by defects in the lens itself, which would require repeated adjustments when replacing different lenses. In addition, the existing adjustment methods are often applied to individual lenses, requiring multiple adjustments for lens groups. Summary of the Invention
[0004] The purpose of this invention is to provide an optical axis adjustment device for a microscope optical system, so as to solve the problem that the prior art lacks adjustment and detection of defects in the lens itself and cannot adjust the lens group.
[0005] To achieve the above objectives, the present invention provides the following technical solution: The optical axis adjustment device of the micromirror optical system includes a worktable, an adjustment block is installed on the worktable, a feeding component is provided on the adjustment block, an adjustment component and a cleaning component are provided on the feeding component, and a detection component is provided on the worktable; The adjusting components include a clamping seat, a pressure ring, a clamping elastic element, a contact plate, a fine-tuning telescopic element, a marking hole, and a laser. The adjusting block is connected to a clamping seat via a feeding component. A pressure ring is detachably installed on the clamping seat. Multiple clamping elastic elements are installed on the pressure ring. A contact plate is installed at the end of each clamping elastic element. A fine-tuning telescopic component is installed on the clamping seat. A marking hole is opened on the clamping seat. A laser is installed on the clamping seat. The adjustment device is controlled by an external control terminal. When the optical axis of the lens needs to be adjusted, the lens is placed on the clamping seat and fixed with a pressure ring on top of the clamping seat. The upper surface of the lens contacts the contact plate and the lower surface contacts the fine-tuning telescopic rod. Then, the lens is transported to the detection station of the detection piece through the feeding component. The imaging detection determines whether the optical axis is tilted. When the optical axis is tilted, the fine-tuning telescopic rod is extended or retracted according to the detection result to tilt the lens slightly and make the optical axis vertical (or parallel to the mechanical reference). When the detection component detects that the optical axis is vertical, it sends feedback to the control terminal. The control terminal controls the laser to emit a laser beam that passes through the marking hole to mark the lens. At the same time, the control terminal records the extension and retraction state of the fine-tuning telescopic component. Combined with the marking point, the control terminal judges the tilt state of the optical axis of the lens, which facilitates the subsequent adjustment of the lens mount or the reprocessing of the lens to make the optical axis vertical in use. By adjusting the lens tilt using the flexible fixing of the elastic element and the fine-tuning telescopic rod, the tilt of the lens optical axis can be determined, thus guiding the specific adjustments during subsequent lens installation. By fine-tuning the length of the telescopic rod, the influence of the lens tilt on the optical axis can be determined, and the optical axis can be adjusted to a vertical state to compensate for the lens's own defects. A single lens can be placed directly on the clamp for testing and adjustment. When the lens group needs to be adjusted, the two lenses are placed on the two clamps respectively, and the two lenses are moved to the coaxial position. By adjusting the state of the two lenses at the same time, the verticality of the optical axis formed by the lens group is ensured. The adjustment of the larger lens can be compensated by the different adjustments of the two lenses, avoiding the waste of lenses caused by the adjustment of a single lens exceeding the limit. It has a wider range of applications.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example: Figures 1-8 As shown, the present invention provides a technical solution for an optical axis adjustment device for a microscope optical system. The optical axis adjustment device for the microscope optical system includes a worktable 1, an adjustment block 2 installed on the worktable 1, a feeding component 3 provided on the adjustment block 2, an adjustment component 4 and a cleaning component 5 provided on the feeding component 3, and a detection component 6 provided on the worktable 1. Adjustment component 4 includes a clamping seat 401, a pressure ring 402, a clamping elastic component 403, a contact plate 404, a fine-tuning telescopic component 405, a marking hole 406, and a laser 407; The adjusting block 2 is connected to the clamping seat 401 via the feeding component 3. The clamping seat 401 is detachably mounted with a pressure ring 402. Multiple clamping elastic elements 403 are mounted on the pressure ring 402. A contact plate 404 is mounted on the end of the clamping elastic element 403. A fine-tuning telescopic element 405 is mounted on the clamping seat 401. A marking hole 406 is opened on the clamping seat 401. A laser 407 is mounted on the clamping seat 401.
[0020] The adjustment device is controlled by an external control terminal. When the optical axis of the lens needs to be adjusted, the lens is placed on the clamping seat 401 and fixed by a pressure ring 402 on top of the clamping seat 401. The upper surface of the lens contacts the contact plate 404 and the lower surface contacts the fine adjustment telescopic rod. Then, the lens is transported to the detection station of the detection component 6 through the feeding component 3. The optical axis is determined by imaging detection. When the optical axis is detected to be tilted, the fine adjustment telescopic rod is extended or retracted according to the detection result to make the lens tilt slightly and make the optical axis vertical (or parallel to the mechanical reference). When the detection element 6 detects that the optical axis is vertical, the detection element 6 sends feedback to the control end. The control end controls the laser 407 to emit a laser through the marking hole 406 to mark the lens. At the same time, the control end records the extension and retraction state of the fine adjustment telescopic element 405. Combined with the marking point, the optical axis tilt state of the lens is determined, which facilitates the subsequent adjustment of the lens mount or the reprocessing of the lens to make the optical axis vertical in use. By using the flexible fixing of the elastic element 403 and the adjustment of the lens tilt by the fine-tuning telescopic rod, the tilt of the lens optical axis can be determined. By adjusting the length of the telescopic rod, the influence of the lens tilt on the optical axis can be determined, and the optical axis can be adjusted to a vertical state to compensate for the lens's own defects. A single lens can be placed directly on the clamp 401 for testing and adjustment. When the lens group needs to be adjusted, the two lenses are placed on the two clamps 401 respectively, and the two lenses are moved to the coaxial position. By adjusting the state of the two lenses at the same time, the verticality of the optical axis formed by the lens group is ensured. The adjustment amount of the lens with a larger adjustment amount can be compensated by the different adjustments of the two lenses, avoiding the waste of lenses caused by the adjustment of a single lens exceeding the limit. It has a wider range of applications.
[0021] Four fine-tuning telescopic components 405 are evenly installed on the clamping base 401, and the four fine-tuning telescopic components 405 are arranged in a circle along the clamping base 401.
[0022] Four fine-tuning telescopic rods are evenly installed on the clamping base 401. Different degrees of tilting of the lens can be achieved by using different lengths of each fine-tuning telescopic rod, while ensuring the lens is fixed, thereby further improving the adjustment accuracy.
[0023] The feeding component 3 includes a vertical plate 301, a module slide rail 302, a slide rail slider 303, a motor base 304, a rotary motor 305, and a rotating rod 306; A vertical plate 301 is installed on the workbench 1. Two module slide rails 302 are symmetrically installed on the vertical plate 301. Slide rail sliders 303 are slidably installed on both module slide rails 302. A motor base 304 is installed on the slide rail slider 303. A rotary motor 305 is installed on the motor base 304. A rotating rod 306 is rotatably installed on the motor base 304. The rotating rod 306 is connected to the output shaft of the rotary motor 305. A clamping seat 401 is installed at the end of the rotating rod 306.
[0024] When adjusting and testing a lens, light needs to pass through the lens. Therefore, optical instruments are often installed above or below the lens, which makes it inconvenient to install the lens. like Figure 5 As shown, in the initial state, the clamping base 401 is located on the outside, and the two clamping bases 401 are located on different horizontal planes, which facilitates the installation of the lens. After installation, the rotary motor 305 is started by controlling the control terminal, which drives the lens to move towards the center. When adjusting the two lenses, the two lenses are made to be in a coaxial state, as shown. Figure 8 As shown; After the rotation is completed, based on the actual spacing between the two lenses in use, the control module slider is moved along the module slide rail 302 to make the two lenses the same as the actual spacing in use, which can ensure the adjustment accuracy. When adjusting two lenses, if the lenses are coaxial, the two 406 marking holes also need to be coaxial. This provides a reference point during installation, facilitates subsequent installation, and improves the quality of optical axis adjustment.
[0025] The cleaning component 5 includes a guide rail base 501, an arc-shaped guide rail 502, an arc-shaped slider 503, an arc-shaped rack 504, a drive gear 505, a mounting base 506, a lower wiping telescopic component 507, an upper wiping telescopic component 508, a wiping component 512, and a transmission component 7. Two guide rail seats 501 are installed on the workbench 1. The two guide rail seats 501 are symmetrically installed about the upright plate 301. An arc-shaped guide rail 502 is installed on the guide rail seat 501. An arc-shaped slider 503 is slidably installed on the arc-shaped guide rail 502. An arc-shaped rack 504 is installed on the guide rail seat 501. A drive gear 505 is rotatably installed on the arc-shaped slider 503. The drive gear 505 meshes with the arc-shaped rack 504. A mounting seat 506 is installed on the arc-shaped slider 503. An upper wiping telescopic component 508 and a lower wiping telescopic component 507 are installed on the mounting seat 506. Wiping components 512 are installed at the ends of both the upper wiping telescopic component 508 and the lower wiping telescopic component 507. A transmission component 7 is installed on the mounting seat 506.
[0026] When the clamping seat 401 moves the lens to the detection position, the rotating rod 306 will drive the arc-shaped slider 503 to slide along the arc-shaped guide rail 502. At the same time, the drive gear 505 will rotate because it meshes with the arc-shaped rack 504. The drive gear 505 drives the upper wiping telescopic component 508 and the lower wiping telescopic component 507 through the transmission component 7 to drive the wiping component 512 to wipe and clean the lens from top to bottom, so as to avoid the debris stuck to the lens during transportation or placement from affecting the optical path and further ensure the adjustment accuracy.
[0027] Cleaning component 5 also includes an angle sensor 509, a linkage rod 510, and a clamping cylinder 511; A clamping cylinder 511 is installed on the arc-shaped slider 503, a linkage rod 510 is installed on the rotating rod 306, an angle sensor 509 is installed on the linkage rod 510, and the angle sensor 509 is coaxially installed with the output shaft of the rotary motor 305.
[0028] When the rotary motor 305 drives the clamping seat 401 to rotate, the linkage rod 510 rotates synchronously. When the linkage rod 510 enters the stroke of the arc-shaped guide rail 502, the angle sensor 509 sends an electrical signal to control the clamping cylinder 511 to clamp the linkage rod 510, so that the wiping cloth and the lens move synchronously for wiping.
[0029] The transmission component 7 includes a lower transmission flat gear 701, a lower driven flat gear 702, a vertical transmission rod 703, a horizontal transmission bevel gear 704, a vertical transmission bevel gear 705, a horizontal transmission rod 706, a horizontal driven bevel gear 707, and a vertical driven bevel gear 708. A lower drive spur gear 701 is mounted on the mounting base 506, and the lower drive spur gear 701 is connected to the drive gear 505. A lower wiping telescopic component 507 is mounted on the lower drive spur gear 701. A lower driven spur gear 702 is mounted on the mounting base 506, and the lower drive spur gear 701 meshes with the lower driven spur gear 702. A vertical drive rod 703 is coaxially mounted on the lower driven spur gear 702. A horizontal drive bevel gear 704 is mounted on the mounting base 506, and the horizontal drive bevel gear 704 is coaxially connected to the vertical drive rod 703. The mounting base 506 is equipped with... A vertical drive bevel gear 705 meshes with a horizontal drive bevel gear 704. A horizontal drive rod 706 is coaxially mounted on the horizontal drive bevel gear 704. A horizontal driven bevel gear 707 is mounted on a mounting base 506 and is connected to the horizontal drive bevel gear 704 via the horizontal drive rod 706. A vertical driven bevel gear 708 is mounted on the mounting base 506 and meshes with the horizontal driven bevel gear 707. An upper wiping telescopic component 508 is mounted on the vertical driven bevel gear 708.
[0030] The drive gear 505 rotates as the arc-shaped slider 503 slides due to its meshing with the arc-shaped rack 504. The drive gear 505 drives the lower transmission flat gear 701 to rotate synchronously. The lower transmission flat gear 701 drives the lower wiping telescopic component 507 to rotate. The lower transmission flat gear 701 drives the lower driven flat gear 702 to rotate through gear meshing. The lower driven flat gear 702 drives the horizontal transmission bevel gear 704 to rotate through the vertical transmission rod 703. The rotation of the horizontal transmission bevel gear 704 drives the vertical transmission bevel gear 705 to rotate through bevel gear meshing. The rotation of the vertical transmission bevel gear 705 drives the upper wiping telescopic component 508 to rotate through the horizontal transmission rod 706, the horizontal driven bevel gear 707, and the vertical driven bevel gear 708. Thus, the movement of the lens drives the wiping component 512 to rotate up and down while moving with the lens, improving the cleaning effect and further improving the adjustment quality.
[0031] The testing component 6 includes a testing interferometer 601, a first-stage reflector 602, a spherical reflector 603, and a moving platform 604; The workbench 1 is equipped with a detection interferometer 601, a first-stage reflector 602 and a moving platform 604. A spherical reflector 603 is installed on the moving platform 604. The detection interferometer 601 and the first-stage reflector 602 are located on the same horizontal plane, and the spherical reflector 603 is located below the first-stage reflector 602.
[0032] The detection component 6 also includes a positioning interferometer 605, a positioning interferometer light guide element 606, and a plane mirror 607; A positioning interferometer 605 and a positioning interferometer light guide element 606 are installed on the workbench 1. A plane mirror 607 is installed on the moving platform 604. The positioning interferometer 605 and the positioning interferometer light guide element 606 are located on the same horizontal plane. The plane mirror 607 is closer to the positioning interferometer 605 than the spherical mirror 603.
[0033] Before adjustment, turn on the detection interferometer 601 and adjust the first-stage reflector 602 so that the test light shines on the plane reflector 607. The laser wavefront is then collimated and returned, passing through the optical system and the plane reflector 607 again before entering the detector of one side of the interferometer. Then, the plane reflector 607 and the spherical reflector are moved synchronously so that the spherical reflector 603 is in the position of the plane reflector 607. At this time, the positioning interferometer 605 and the positioning interferometer light guide element 606 need to be adjusted to ensure that the plane reflector 607 can return the positioning interferometer 605 to the detector of the positioning interferometer 605. At this time, the interference pattern fringes of the positioning interferometer 605 are 0. Then, the optical axis tilt is detected. When the interference fringes of the positioning interferometer 605 change, it indicates that there is a deviation in the detection optical path. The detection component 6 needs to be adjusted to further ensure the detection accuracy. During testing, the detection interferometer 601 emits detection light, which passes through the first-stage reflector 602, the lens to be tested, and the spherical reflector 603 before returning to the detector of the detection interferometer 601. When fringes appear, it indicates that the optical axis is tilted. At this time, the lens is adjusted by the adjustment component 4 until the optical axis is vertical (i.e., perpendicular to the mechanical reference in actual use).
[0034] Working principle of the invention: The adjustment device is controlled by an external control terminal. When the optical axis of the lens needs to be adjusted, the lens is placed on the clamping seat 401 and fixed by a pressure ring 402 on top of the clamping seat 401. The upper surface of the lens contacts the contact plate 404 and the lower surface contacts the fine adjustment telescopic rod. Then, the lens is transported to the detection station of the detection component 6 through the feeding component 3. The optical axis is determined by imaging detection. When the optical axis is detected to be tilted, the fine adjustment telescopic rod is extended or retracted according to the detection result to make the lens tilt slightly and make the optical axis vertical (or parallel to the mechanical reference). When the detection element 6 detects that the optical axis is vertical, the detection element 6 sends feedback to the control end. The control end controls the laser 407 to emit a laser through the marking hole 406 to mark the lens. At the same time, the control end records the extension and retraction state of the fine adjustment telescopic element 405. Combined with the marking point, the optical axis tilt state of the lens is determined, which facilitates the subsequent adjustment of the lens mount or the reprocessing of the lens to make the optical axis vertical in use. By using the flexible fixing of the elastic element 403 and the adjustment of the lens tilt by the fine-tuning telescopic rod, the tilt of the lens optical axis can be determined. By adjusting the length of the telescopic rod, the influence of the lens tilt on the optical axis can be determined, and the optical axis can be adjusted to a vertical state to compensate for the lens's own defects. A single lens can be placed directly on the clamp 401 for testing and adjustment. When the lens group needs to be adjusted, the two lenses are placed on the two clamps 401 respectively, and the two lenses are moved to the coaxial position. By adjusting the state of the two lenses at the same time, the verticality of the optical axis formed by the lens group is ensured. The adjustment amount of the lens with a larger adjustment amount can be compensated by the different adjustments of the two lenses, avoiding the waste of lenses caused by the adjustment of a single lens exceeding the limit. It has a wider range of applications.
[0035] When adjusting and testing a lens, light needs to pass through the lens. Therefore, optical instruments are often installed above or below the lens, which makes it inconvenient to install the lens. like Figure 5 As shown, in the initial state, the clamping base 401 is located on the outside, and the two clamping bases 401 are located on different horizontal planes, which facilitates the installation of the lens. After installation, the rotary motor 305 is started by controlling the control terminal, which drives the lens to move towards the center. When adjusting the two lenses, the two lenses are made to be in a coaxial state, as shown. Figure 8 As shown; After the rotation is completed, based on the actual spacing between the two lenses in use, the control module slider is moved along the module slide rail 302 to make the two lenses the same as the actual spacing in use, which can ensure the adjustment accuracy. When adjusting two lenses, if the lenses are coaxial, the two 406 marking holes also need to be coaxial. This provides a reference point during installation, facilitates subsequent installation, and improves the quality of optical axis adjustment.
[0036] When the clamping seat 401 moves the lens to the detection position, the rotating rod 306 will drive the arc-shaped slider 503 to slide along the arc-shaped guide rail 502. At the same time, the drive gear 505 will rotate because it meshes with the arc-shaped rack 504. The drive gear 505 drives the upper wiping telescopic component 508 and the lower wiping telescopic component 507 through the transmission component 7 to drive the wiping component 512 to wipe and clean the lens from top to bottom, so as to avoid the debris stuck to the lens during transportation or placement from affecting the optical path and further ensure the adjustment accuracy.
[0037] When the rotary motor 305 drives the clamping seat 401 to rotate, the linkage rod 510 rotates synchronously. When the linkage rod 510 enters the stroke of the arc-shaped guide rail 502, the angle sensor 509 sends an electrical signal to control the clamping cylinder 511 to clamp the linkage rod 510, so that the wiping cloth and the lens move synchronously for wiping.
[0038] Before adjustment, turn on the detection interferometer 601 and adjust the first-stage reflector 602 so that the test light shines on the plane reflector 607. The laser wavefront is then collimated and returned, passing through the optical system and the plane reflector 607 again before entering the detector of one side of the interferometer. Then, the plane reflector 607 and the spherical reflector are moved synchronously so that the spherical reflector 603 is in the position of the plane reflector 607. At this time, the positioning interferometer 605 and the positioning interferometer light guide element 606 need to be adjusted to ensure that the plane reflector 607 can return the positioning interferometer 605 to the detector of the positioning interferometer 605. At this time, the interference pattern fringes of the positioning interferometer 605 are 0. Then, the optical axis tilt is detected. When the interference fringes of the positioning interferometer 605 change, it indicates that there is a deviation in the detection optical path. The detection component 6 needs to be adjusted to further ensure the detection accuracy. During testing, the detection interferometer 601 emits detection light, which passes through the first-stage reflector 602, the lens to be tested, and the spherical reflector 603 before returning to the detector of the detection interferometer 601. When fringes appear, it indicates that the optical axis is tilted. At this time, the lens is adjusted by the adjustment component 4 until the optical axis is vertical (i.e., perpendicular to the mechanical reference in actual use).
