Description

Technical Field

[0001] This application relates to the field of optical instrument technology, and in particular to a multi-dimensional adjustment device for lens adjustment and testing. Background Technology

[0002] In the debugging of high-performance optical lenses, the core purpose of aligning the optical axis of the lens with that of the laser interferometer is to eliminate the interference of optical axis offset on the detection accuracy. Only when the optical axis lines of the two are completely collinear can the laser interferometer accurately capture the true optical performance of the lens and avoid the distortion of detection data caused by axis offset. This process is essentially achieved by coordinating mechanical adjustment and optical feedback to make the optical center axis of the lens and the laser center propagation axis of the interferometer completely aligned.

[0003] Traditional lens adjustment and testing devices can only adjust the lens optical axis when it is aligned with the laser interferometer's optical axis. Furthermore, for optical axis adjustment, the lens adjustment mount only supports adjustments in a few dimensions, such as X-axis and Y-axis translation. For lenses with multi-angle optical axes, such as those with one eyepiece and three objectives, where the objectives face different directions, traditional lens adjustment devices lack the ability to precisely adjust in multiple directions, such as the Z-axis. This makes it impossible to ensure complete alignment between the lens's optical axis and the interferometer's optical axis. Moreover, existing adjustment methods only adjust the lens or the interferometer, resulting in a limited range of adjustment methods and dimensions, restricted freedom of adjustment, and an inability to achieve the alignment required for high-precision adjustment, thus failing to meet the needs of multi-degree-of-freedom calibration. Utility Model Content

[0004] To achieve compatibility with various lenses and precise adjustment with multiple degrees of freedom, this application provides a multi-dimensional adjustment device for lens debugging and testing.

[0005] This application provides a multi-dimensional adjustment device for lens adjustment and testing. The technical solution adopted is as follows: A multi-dimensional adjustment device for lens adjustment and testing includes a laser interferometer, a guide rail on one side of the laser interferometer, two first adjustment plates slidably disposed on the guide rail, and a first forward and backward moving component disposed on the guide rail, the first forward and backward moving component being used to drive the first adjustment plates to move forward and backward. The first adjusting plate is provided with a rotating component, and the rotating component is provided with a second adjusting plate. The rotating component is used to drive the second adjusting plate to rotate. A third adjustment plate is slidably disposed on the second adjustment plate, and a left-right moving component is disposed between the second adjustment plate and the third adjustment plate. The left-right moving component is used to drive the third adjustment plate to move left and right relative to the second adjustment plate. The third adjusting plate is provided with a first lifting component, and the first lifting component is provided with a fourth adjusting plate. The first lifting component is used to drive the fourth adjusting plate to move up and down. The fourth adjustment plate is provided with an angle adjustment component. One of the angle adjustment components is fixedly equipped with a reflector, and the other angle adjustment component is equipped with a clamping component. The angle adjustment component is used to drive the tilt angle adjustment of the lens under test and the reflector, and the clamping component is used to clamp the lens under test.

[0006] By adopting the above technical solution, after the lens under test is placed on the adjustment stage, it is clamped and secured using a clamping assembly. Then, the lens is moved and adjusted by adjusting the first forward and backward moving assembly, the left and right moving assembly, the lifting moving assembly, and the rotating assembly. In addition, the angle adjustment assembly is used to adjust in five dimensions. At the same time, the reflector can be adjusted in multiple dimensions. Multiple adjustment angles and multiple adjustment methods work together to achieve multi-dimensional free adjustment, improve the adjustment capability of the lens debugging and testing device, break through the adjustment limitations when testing angle, help eliminate the interference of optical axis offset on the detection accuracy, facilitate the laser interferometer to accurately capture the true optical performance of the lens, avoid the distortion of detection data caused by axis offset, and significantly improve the multi-dimensional adjustment accuracy of the adjustment device.

[0007] Optionally, the first forward and backward moving component includes a first adjusting knob located at the end of the guide rail. A moving worm is fixedly provided at one end of the first adjusting knob. A lead screw is provided inside the guide rail. A moving worm wheel is fixedly provided at the end of the lead screw near the first adjusting knob. The moving worm and the moving worm wheel are meshed together. A moving sleeve is threadedly connected to the end of the lead screw away from the moving worm wheel. The moving sleeve is fixedly connected to the first adjusting plate. The left-right moving component, the first lifting component, and the first forward-backward moving component have the same structure.

[0008] By adopting the above technical solution, when the lens under test needs to be moved back and forth for adjustment, rotating the first adjustment knob drives the moving worm gear to rotate, which in turn drives the moving worm wheel to rotate. The moving worm wheel then drives the lead screw to rotate, which in turn drives the moving sleeve to move the first adjustment plate back and forth on the guide rail. Similarly, when the lens under test needs to be moved left and right or up and down, rotating the corresponding adjustment knob will adjust the lens under test. Multiple dimensional adjustments do not interfere with each other. When adjusting one dimension, other dimensions are not affected, preventing the adjustment of one direction from affecting other directions when multiple dimensions are coupled, avoiding repeated adjustments, simplifying operation and improving adjustment efficiency.

[0009] Optionally, the angle adjustment assembly includes a semi-circular platform, which is fixedly mounted on the fourth adjustment plate. An adjustment platform is slidably mounted on the semi-circular platform. An adjustment worm gear is fixedly mounted in the middle of the semi-circular platform. An adjustment worm is rotatably mounted on the side of the adjustment platform facing the adjustment worm gear. The adjustment worm gear and the adjustment worm are meshed together. A second adjustment knob is fixedly mounted on one end of the adjustment worm.

[0010] By adopting the above technical solution, the angle adjustment component can adjust the tilt angle of the lens. When it is necessary to adjust the tilt angle of the lens being tested, the second adjustment knob is turned. The second adjustment knob drives the adjustment worm gear to rotate. The adjustment worm wheel is fixed on the semicircular platform, so that the adjustment worm gear moves along the arc surface of the semicircular platform, thereby driving the lens to adjust the tilt angle.

[0011] Optionally, scale lines are provided on the arcs on both sides of the semicircular platform, and arrow marks are provided on both sides of the adjustment platform at the connection positions with the semicircular platform, with the arrow marks pointing to the scale lines.

[0012] By adopting the above technical solution, the scale lines are set on the arc surface of the semi-circular frustum. When adjusting the lens tilt angle, the arrow marks point directly to the scale lines. The scale lines, together with the arrow marks, convert uncertain angles into angle values. During operation, the adjustment angle can be displayed intuitively, making it easy to accurately grasp the angle adjustment degree and achieve precise adjustment control. At the same time, for the same type of lens under test, the clear scale lines and arrow marks can quickly complete the initial positioning, simplify the operation process, reduce adjustment time, and improve adjustment efficiency.

[0013] Optionally, the clamping assembly includes a third adjustment knob, one end of which is fixedly provided with a rotating gear. The rotating gear is rotatably mounted on the adjustment platform. Two racks are meshed on the rotating gear and are arranged opposite to each other. A clamping arm is provided on the rack, and the clamping arm is used to clamp the lens under test.

[0014] By adopting the above technical solution, when the lens under test needs to be placed on the adjustment table, first rotate the third adjustment knob. The third adjustment knob drives the rotating gear to rotate, and the rotating gear drives the rack to move horizontally, so that the two clamping arms move away from each other. This ensures that lenses of different sizes can be placed smoothly on the adjustment table and prevents the lens from colliding due to the small distance between the two clamping arms. Then, rotate the third adjustment knob again to clamp the lens under test between the two clamping arms. This ensures that the lens under test is stably fixed on the adjustment table during subsequent adjustments and avoids the adjustment failure caused by the movement of the lens under test during the adjustment process.

[0015] Optionally, the rotating assembly includes a rotating motor, which is fixedly mounted on a first adjusting plate. A turntable is rotatably connected to the rotating motor, and the turntable is fixedly connected to the second adjusting plate.

[0016] By adopting the above technical solution, when the lens under test needs to be rotated and adjusted, a rotary motor is used to drive the lens under test to rotate. The rotary motor can ensure that the lens under test is rotated to the specified position, thereby achieving precise control.

[0017] Optionally, a slide rail is provided on the side of the guide rail, and a second forward and backward moving component is provided on the slide rail. The second forward and backward moving component has the same structure as the first forward and backward moving component. A first moving plate is provided on the second forward and backward moving component, and a second lifting component is provided on the first moving plate. The second lifting component has the same structure as the first lifting component, and a second moving plate is provided on the second lifting component. The laser interferometer is fixedly mounted on the second moving plate.

[0018] By adopting the above technical solution, not only can the lens under test be adjusted, but the laser interferometer can also be moved back and forth and up and down, realizing multiple adjustment methods. The laser interferometer and the lens under test are adjusted in coordination, improving adjustment efficiency and reducing adjustment difficulty.

[0019] Optionally, both the slide rail and the guide rail are equipped with digital display grating rulers, which are used for rapid positioning of the optical axis.

[0020] By adopting the above technical solution, the digital display grating ruler can achieve ultra-high precision displacement measurement. During the optical axis positioning process, high-precision measurement ensures the accuracy of the optical axis position, avoids reliance on operator visual inspection during the positioning process, effectively eliminates human error, and at the same time, the digital display grating ruler can display adjustment movement information in real time, intuitively and quickly understand the adjustment changes, realize visual adjustment, and improve the reliability of the adjustment device.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After placing the lens under test on the adjustment stage, clamp it securely using the clamping assembly. Then, adjust the lens by moving it forward and backward, left and right, lifting and lowering, and rotating. Combine this with the angle adjustment assembly to make adjustments in five dimensions. Simultaneously, the reflector can be adjusted in multiple dimensions. Multiple adjustment angles and multiple adjustment methods work together to achieve free adjustment in multiple dimensions, improving the adjustment capability of the lens debugging and testing device, breaking through the adjustment limitations when testing angles, helping to eliminate the interference of optical axis offset on the testing accuracy, and enabling the laser interferometer to accurately capture the true optical performance of the lens. This avoids the distortion of testing data caused by axis offset and significantly improves the accuracy of multi-dimensional adjustment of the adjustment device.

[0022] 2. When the lens under test needs to be moved forward or backward, rotate the first adjustment knob. The first adjustment knob drives the moving worm gear to rotate, which in turn drives the moving worm wheel to rotate. The moving worm wheel drives the lead screw to rotate, which in turn drives the moving sleeve to move the first adjustment plate forward or backward on the guide rail. Similarly, when the lens under test needs to be moved left or right or up or down, rotate the corresponding adjustment knob to adjust the lens under test. Multiple dimensional adjustments do not interfere with each other. When adjusting one dimension, other dimensions are not affected, preventing the adjustment of one direction from affecting other directions when multiple dimensions are coupled, avoiding repeated adjustments, simplifying operation and improving adjustment efficiency. The angle adjustment component can adjust the tilt angle of the lens. When the tilt angle of the lens under test needs to be adjusted, rotate the second adjustment knob. The second adjustment knob drives the adjustment worm gear to rotate. The adjustment worm wheel is fixed on the semicircular platform, causing the adjustment worm gear to move along the arc surface of the semicircular platform, thus adjusting the tilt angle of the lens. When the lens under test needs to be rotated, a rotary motor is used to rotate the lens under test. The rotary motor can ensure that the lens under test is rotated to the specified position, achieving precise control.

[0023] 3. Not only can the lens under test be adjusted, but the laser interferometer can also be moved back and forth and up and down to achieve multiple adjustment methods. The laser interferometer and the lens under test are adjusted in coordination to improve adjustment efficiency and reduce adjustment difficulty.

[0024] 4. When placing the lens under test on the adjustment table, first rotate the third adjustment knob. The third adjustment knob drives the rotating gear to rotate, which in turn drives the rack to move horizontally, causing the two clamping arms to move away from each other. This ensures that lenses of different sizes can be placed smoothly on the adjustment table and prevents the lens from colliding due to insufficient distance between the two clamping arms. Then, rotate the third adjustment knob again to clamp the lens under test between the two clamping arms. This ensures that the lens under test is stably fixed on the adjustment table during subsequent adjustments and prevents the lens from moving during the adjustment process, which could lead to adjustment failure.

[0025] 5. By using the arc surface of the semi-circular frustum to set the scale lines, when adjusting the lens tilt angle, the arrow marks point directly to the scale lines. The scale lines, together with the arrow marks, convert uncertain angles into angle values. During operation, the adjusted angle can be displayed intuitively, facilitating accurate grasp of the angle adjustment degree and achieving precise adjustment control. At the same time, for lenses of the same type under test, the clear scale lines and arrow marks can quickly complete the initial positioning, simplifying the operation process, reducing adjustment time, and improving adjustment efficiency. The digital display grating ruler can achieve ultra-high precision displacement measurement accuracy. During the optical axis positioning process, high-precision measurement ensures the accuracy of the optical axis position, avoiding reliance on operator visual inspection during positioning and effectively eliminating human error. At the same time, the digital display grating ruler can display adjustment movement information in real time, intuitively and quickly understanding the adjustment changes, realizing visual adjustment, and improving the reliability of the adjustment device.
