Description

Technical Field

[0001] This utility model relates to the field of optical engineering technology, and in particular to a primary and secondary mirror assembly and adjustment device. Background Technology

[0002] In the construction and application of optical systems, from basic microscopes that help researchers explore the microscopic world to large astronomical telescopes capturing the faint light from distant galaxies; from photolithography machines used for precision machining to ensure high-precision chip manufacturing to medical imaging equipment providing clear images for disease diagnosis, the primary and secondary mirrors, as key optical components, are crucial for ensuring the imaging quality and performance of the optical system through precise assembly and adjustment. Even minute deviations in the primary and secondary mirrors can alter the light propagation path, leading to problems such as blurred images, reduced resolution, and image distortion, severely impacting the practical application of optical systems in numerous fields, including scientific research, industrial production, and medicine. Therefore, developing high-precision, reliable, and easy-to-operate primary and secondary mirror assembly and adjustment devices has always been a vital and ongoing research and development challenge in the field of optical engineering.

[0003] The main problems with existing primary and secondary mirror assembly and adjustment devices include:

[0004] Insufficient structural stability: During assembly and adjustment, the device structure is prone to deformation or displacement due to external vibrations, temperature changes, and other factors. This causes changes in the relative positions and angles of the primary and secondary mirrors, affecting assembly and adjustment accuracy. This problem is particularly prominent in large optical systems. Your solution's unique vibration-damping structure and robust connections between components effectively enhance structural stability and reduce interference from external factors.

[0005] Limited adjustment precision: Traditional mechanical adjustment methods and simple guide rail structures are insufficient for achieving high-precision position and angle adjustments. Even with automated assembly and adjustment technology, limitations in sensor accuracy and control algorithms still prevent the adjustment precision from meeting the requirements of some high-end optical systems.

[0006] High operational complexity: Although some assembly and adjustment devices have high adjustment accuracy, their operation is complex and requires operators to have professional knowledge and skills. Moreover, the assembly and adjustment process requires frequent parameter adjustments and measurements, which is time-consuming and affects work efficiency.

[0007] Lack of real-time monitoring and feedback mechanisms: Existing assembly and adjustment devices often lack real-time monitoring and feedback mechanisms for the position and optical accuracy of the primary and secondary mirrors during the assembly and adjustment process. Operators can only perform inspections after assembly and adjustment are completed. Once a problem is found, the assembly and adjustment need to be repeated, increasing the cost and time of assembly and adjustment.

[0008] Therefore, a primary and secondary mirror adjustment device is needed to solve the above problems. Utility Model Content

[0009] The purpose of this invention is to address the shortcomings of existing technologies by proposing a primary and secondary mirror mounting and adjusting device.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: a primary and secondary mirror mounting device, comprising an optical platform, a support adjustment rod, and a support frame. The top of the optical platform is bolted to the support adjustment rod, and the top of the support adjustment rod is mounted on the support frame. An interferometer is slidably connected to the top of the support frame. A reflection adjustment frame is mounted on one side of the top of the support frame. An adjustment plate is mounted on the front of the reflection adjustment frame, and a 45° reflector is mounted on the front of the adjustment plate. A structural component is mounted on one side of the top of the optical platform.

[0011] Preferably, a standard plane mirror is installed at the bottom of the structural component, an angle sensor is installed at the middle of the bottom end of the standard plane mirror, threaded adjustment rods are installed on both sides and the front of the bottom of the standard plane mirror, a base is installed at the bottom of the threaded adjustment rods, and the base is installed on one side of the top of the optical platform.

[0012] Preferably, a primary mirror adjustment slide is installed on the bottom side of the structural component near the top of the standard plane mirror, and the primary mirror is slidably connected to the top of the primary mirror adjustment slide. A secondary mirror mounting bracket is installed on one side of the top of the structural component, and a secondary mirror is installed on the top of the secondary mirror mounting bracket.

[0013] Preferably, the reflective adjustment frame is L-shaped, and connecting springs are provided at the top and front of the reflective adjustment frame and the connection point with the adjustment plate, so that the adjustment plate and the reflective adjustment frame attract each other directly.

[0014] Preferably, a drive motor is installed on one side of the reflection adjustment frame, a drive shaft is connected to the front of the drive motor, and a sleeve is installed on the outside of the drive shaft.

[0015] Preferably, a connecting arm is installed at both the top and bottom of the sleeve, and the connecting arm is engaged with the back of the adjusting plate.

[0016] Preferably, the optical platform is composed of alternating layers of rubber and foam metal.

[0017] Beneficial effects

[0018] In this invention, the overall equipment significantly improves assembly and adjustment accuracy and stability through a unique structural design. The optical platform employs an alternating structure of rubber and foam metal layers, effectively absorbing external vibrations and providing a stable foundation for the entire assembly and adjustment process. This greatly reduces the risk of structural deformation and displacement caused by vibration, ensuring the stability of the relative position and angle of the primary and secondary mirrors, thereby improving assembly and adjustment accuracy. Regarding adjustment accuracy, the dovetail groove at the top of the frame, combined with the slider structure and locking bolts, ensures precise and stable adjustment of the interferometer's position. The 45° reflector is connected to the reflection adjustment frame via a connecting spring and a mutually attracting structure, enabling flexible and precise angle adjustment. The primary mirror adjustment slide precisely adjusts the primary mirror's position, and in conjunction with the precision adjustment mechanism within the reflection adjustment frame, consisting of a drive motor, drive shaft, sleeve, and connecting arm, it allows for precise fine-tuning of the relative optical paths of the primary and secondary mirrors. These designs effectively overcome the limited accuracy problems of traditional mechanical adjustments and simple guide rail structures, meeting stringent accuracy requirements even in the assembly and adjustment of high-end optical systems.

[0019] This invention offers significant advantages in terms of ease of operation and efficiency. Firstly, its overall structure is rationally laid out, and the operation of each adjustment component is simple and easy to understand, reducing the professional knowledge and skills required of operators and allowing for hands-on operation without complex training. For example, the standard plane mirror is installed via a threaded adjustment rod at the bottom and a base; the operator can easily rotate the threaded adjustment rod to adjust its position and angle. The sliding operation of the primary mirror adjustment slide is simple, facilitating quick and easy adjustment of the primary mirror's position. Secondly, the device is equipped with a real-time monitoring and feedback mechanism. The angle sensor at the bottom of the standard plane mirror monitors angle changes in real time, and the interferometer detects optical accuracy in real time. Operators can make timely adjustments based on this real-time data, eliminating the need to discover problems and re-adjust after assembly, greatly saving assembly time and costs and improving assembly efficiency.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0029] Reference Figure 1-4 A primary and secondary mirror mounting device includes an optical platform 1, a support adjustment rod 2, and a lifting frame 3.

[0032] The reflector adjustment frame 5 is L-shaped. Connecting springs 16 are provided at the top and front of the reflector adjustment frame 5 and the connection point with the adjustment plate 13. The adjustment plate 13 and the reflector adjustment frame 5 attract each other directly.

[0033] A drive motor 17 is installed on one side inside the reflection adjustment frame 5. A drive shaft 15 is connected to the front of the drive motor 17. A sleeve 18 is installed on the outside of the drive shaft 15.

[0034] Connecting arms 14 are installed at both the top and bottom of the sleeve 18, and the connecting arms 14 are snapped into the back of the adjusting plate 13.

[0035] The optical platform 1 is composed of rubber layers and foam metal layers arranged alternately.

[0036] Assembly: Fix the interferometer 4 and the support 3 on the optical platform 1, fix the 45° reflector 6 on the support 3, place the interferometer 4 on the support 3, move the interferometer 4 to align it with the incident direction of the 45° reflector 6, fix the interferometer 4, place the standard plane mirror 8 on the optical platform 1, move the standard plane mirror 8 to align it with the refraction direction of the 45° reflector 6, and fix the standard plane mirror 8.

[0037] Calibration: Analyze the detection images of interferometer 4 to determine the optical accuracy between interferometer 4, 45° reflector 6, and standard plane mirror 8. If there is a deviation, adjust the relative angles appropriately until the detection accuracy meets the requirements.

[0038] Assembly and debugging: Install structural component 7 on optical platform 1, aligning the empty space of primary mirror 10 with the refraction direction of 45° reflector 6. Install primary mirror 10 and secondary mirror 12, and simultaneously observe the detected image from interferometer 4 to analyze whether the relative positions of the primary and secondary mirrors and the optical accuracy meet the requirements. If there is any deviation, adjust appropriately until the detection accuracy meets the requirements. Specific Implementation Example 2:

[0040] Reference Figure 1-4 The overall working principle is as follows:

[0041] Assembly principle:

[0042] Based on the stability of the optical platform 1, which is composed of alternating layers of rubber and foam metal, it can effectively absorb vibrations and provide a stable foundation for the entire device. The support adjustment rod 2 is bolted to the top of the optical platform 1 to provide support for the lift 3, and the height and angle of the lift 3 can be finely adjusted by adjusting the bolts.

[0043] The dovetail groove and slider structure set on the top of the support 3 allow the interferometer 4 to move flexibly. After being adjusted to the position aligned with the incident direction of the 45° reflector 6, it is fixed by the set bolt to ensure the stability of the interferometer 4 for subsequent optical testing.

[0044] A 45° reflector 6 is mounted on the adjustment plate 13 of the reflection adjustment frame 5. The adjustment plate 13 and the reflection adjustment frame 5 are connected by a connecting spring 16 and attract each other. This structure allows the adjustment plate 13 to be flexibly adjusted within a certain range. It is fixed to one side of the frame 3 to ensure that the light is reflected along a predetermined path.

[0045] The standard plane mirror 8 is placed on the optical platform 1 and mounted on one side of the optical platform 1 via the threaded adjustment rod 19 at the bottom and the base 21. The position and angle of the standard plane mirror 8 can be adjusted by rotating the threaded adjustment rod 19 so that it is aligned with the refraction direction of the 45° reflector 6, ensuring the normal refraction path of light.

[0046] Calibration principle:

[0047] Interferometer 4 emits light rays, which are reflected by 45° mirror 6 and then reach standard plane mirror 8, before being reflected back to interferometer 4. Interferometer 4 detects the reflected light rays and generates a detection image.

[0048] Based on optical principles, by analyzing information such as interference fringes and phase of light in the detection image, the optical accuracy between the interferometer 4, the 45° reflecting mirror 6, and the standard plane mirror 8 can be determined, such as whether the light propagation path is accurate and whether the reflection angle meets the requirements.

[0049] If the test reveals a deviation in optical accuracy, the angle and position of the standard plane mirror 8 can be changed by adjusting the angle of the adjustment plate 13 on the reflection adjustment frame 5 (using the connecting spring 16 and the structure of mutual attraction), and by rotating the threaded adjustment rod 19 at the bottom of the standard plane mirror 8, so that the optical accuracy of the three can meet the test requirements.

[0050] Assembly and debugging principles:

[0051] The structural component 7 is installed on the optical platform 1. By adjusting its position, the empty space of the primary mirror 10 is aligned with the refraction direction of the 45° reflector 6, ensuring that light can propagate smoothly to the primary mirror 10.

[0052] The primary mirror 10 is mounted on the primary mirror adjustment slide plate 9, and the position of the primary mirror 10 can be adjusted by sliding the primary mirror adjustment slide plate 9; the secondary mirror 12 is mounted on the secondary mirror mounting bracket 11.

[0053] The light emitted by interferometer 4 is refracted by 45° mirror 6 to primary mirror 10, then reflected by primary mirror 10 to secondary mirror 12, and finally reflected back to interferometer 4 by secondary mirror 12. Interferometer 4 detects the reflected light and generates an image.

[0054] The operator observes the image detected by the interferometer 4 and analyzes the relative position and optical accuracy of the primary mirror 10 and the secondary mirror 12, such as whether the distance and angle between the primary and secondary mirrors meet the design requirements, and whether the reflection and propagation of light between the primary and secondary mirrors are normal.

[0055] If the detection reveals a deviation in the relative position or optical accuracy between the primary mirror 10 and the secondary mirror 12, the position of the primary mirror 10 can be changed by adjusting the primary mirror adjustment slide plate 9. Additionally, the drive motor 17 within the reflection adjustment frame 5 can rotate the drive shaft 15 and sleeve 18, thereby adjusting the angle of the adjustment plate 13 (i.e., the 45° reflector 6) via the connecting arm 14. This indirectly fine-tunes the relative optical paths of the primary and secondary mirrors until the detection accuracy meets the requirements. Simultaneously, the angle sensor 20 at the bottom of the standard plane mirror 8 monitors the angle changes of the standard plane mirror 8 in real time, providing data reference for adjustment and ensuring the precision and accuracy of the entire assembly and adjustment process.

[0056] In summary:

[0057] 1. The dovetail groove and slider structure set on the top of the frame 3 in this device allow the interferometer 4 to move flexibly. After being adjusted to the position aligned with the incident direction of the 45° reflector 6, it is fixed by the set bolt to ensure the stability of the position of the interferometer 4 for subsequent optical testing.

[0058] A 45° reflector 6 is mounted on the adjustment plate 13 of the reflection adjustment frame 5. The adjustment plate 13 and the reflection adjustment frame 5 are connected by a connecting spring 16 and attract each other. This structure allows the adjustment plate 13 to be flexibly adjusted within a certain range. It is fixed to one side of the frame 3 to ensure that the light is reflected along a predetermined path.

[0059] 2. Interferometer 4 emits light rays, which are reflected by 45° mirror 6 and then reach standard plane mirror 8, before being reflected back to interferometer 4. Interferometer 4 detects the reflected light rays and generates a detection image.

[0060] Based on optical principles, by analyzing information such as interference fringes and phase of light in the detection image, the optical accuracy between the interferometer 4, the 45° reflecting mirror 6, and the standard plane mirror 8 can be determined, such as whether the light propagation path is accurate and whether the reflection angle meets the requirements.

[0061] If the test reveals a deviation in optical accuracy, the angle and position of the standard plane mirror 8 can be changed by adjusting the angle of the adjustment plate 13 on the reflection adjustment frame 5 (using the connecting spring 16 and the structure of mutual attraction), and by rotating the threaded adjustment rod 19 at the bottom of the standard plane mirror 8, so that the optical accuracy of the three can meet the test requirements.
