Abstract
Description
Technical Field
[0001] This utility model relates to the field of folding optical system technology, and in particular to an approval device for the optical path of a folding optical system. Background Technology
[0002] The working principle of reflective optics is primarily based on the refraction and reflection of light. High dispersion control: Reflective optics uses a dispersion-free reflecting surface instead of a dispersive refractive surface, resulting in excellent dispersion control. Circular optical path: Light travels in a circular pattern as it passes through the lens, thus the out-of-focus blur spot also forms a circular shape. In summary, reflective optical systems achieve long focal lengths and compact structures while maintaining good dispersion control through multiple reflections of light between the lens and mirror. This design is widely used in fields such as astronomical telescopes.
[0003] Most existing folding optical systems rely on visual inspection to determine the accuracy of the optical path, and lack positioning measures for the optical system. This leads to large errors in the judgment results, which in turn affects the production efficiency of the optical system. In addition, the front and back of the verification target rings in existing folding optical systems have the same shape, and the shadows left by the optical beam after passing through the front and back target rings are also the same shape. Therefore, the verification judgment of the optical path is relatively vague, and the accuracy needs to be improved. Utility Model Content

In addition, the front and rear shapes of the approval target rings in existing folding optical systems are the same, and the shadows left by the optical beam after passing through the front and rear target rings are also the same, which makes the approval judgment of the optical path somewhat vague and the accuracy needs to be improved.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides the following technical solution: an approval device for the optical path of a folding optical system, comprising a device base plate 1, a fixed seat 2 and a support column 3. The fixed seat 2 is fixedly connected to the left side of the top surface of the device base plate 1. The support column 3 is installed on the top surface of the fixed seat 2. A movable seat 4 is fixedly installed above the support column 3. A screw 5 is movably inserted into the left side of the top surface of the fixed seat 2. Positioning plates 6 are movably arranged on both sides of the top surface of the movable seat 4. A positioning rod 7 is through the interior of the positioning plate 6. An approval box 8 is fixedly installed on the top surface of the device base plate 1. A front target ring 9 is embedded in the left side surface of the approval box 8, and a rear target ring 10 is embedded in the right side surface of the approval box 8. An imaging plate 11 is fixedly installed on the right side of the top surface of the device base plate 1.
[0029] Reference Figure 1 and Figure 2As shown, specifically, the top surface of the movable seat 4 is provided with a mounting groove 401, and two positioning plates 6 are provided, with the two positioning plates 6 located on both sides of the mounting groove 401 respectively. The surface of the positioning rod 7 is provided with two sets of threads 701, the threads of the two sets of threads 701 are arranged in opposite directions, and the two sets of threads 701 are respectively inserted into the interior of the two positioning plates 6. When the optical system is placed in the mounting groove 401, the positioning rod 7 is rotated, so that the two plates are brought closer to each other under the action of the two sets of reverse threads 701 until the optical system in the mounting groove 401 is clamped, thereby achieving the positioning effect in the optical system verification process and improving the verification accuracy.
[0030] Reference Figure 1 and Figure 3 As shown, specifically, the top end of the screw 5 is movably inserted into the surface of the movable seat 4, and a clamping head 501 is fixedly connected to the top surface of the screw 5. The clamping head 501 is movably attached to the top surface of the movable seat 4. A movable column 301 is movably inserted into the top end of the support column 3, and a spring 302 is fixedly connected to the bottom surface of the movable column 301. The movable column 301 is elastically connected to the inner cavity of the support column 3 through the spring 302. By rotating the screw 5 to move the clamping head 501 downward or upward, the movable seat 4 can be moved closer to or away from the fixed seat 2, thereby realizing the vertical adjustment of the optical system. The structure is simple, highly flexible, and effectively improves the applicability of the approval device.
[0031] Reference Figure 1 and Figure 4 As shown, specifically, a longitudinal baffle 901 is fixedly installed inside the front target ring 9, and a transverse baffle 1001 is fixedly installed inside the rear target ring 10. The centers of the front target ring 9 and the rear target ring 10 are on the same horizontal line. A circular through hole is provided through the surface of both the longitudinal baffle 901 and the transverse baffle 1001. A beam groove 1101 is provided on the surface of the imaging plate 11. The beam groove 1101 is in the shape of a cross. The beam of the optical system passes through the front target ring 9 and the rear target ring 10. After being blocked by the combination of the longitudinal baffle 901 and the transverse baffle 1001, a cross shadow is formed on the surface of the imaging plate 11. If the shadow shadow matches the shape of the beam groove 1101, the beam is considered qualified. The result is clear at a glance. Combined imaging effectively avoids the error caused by visual inspection and improves accuracy.
[0032] The usage process and working principle of this utility model are as follows: First, the optical system is placed in the mounting slot 401. The positioning rod 7 is rotated, causing the two pieces to move closer together under the influence of the two sets of reverse threads 701 until the optical system in the mounting slot 401 is clamped. This achieves a positioning effect during the optical system verification process, improving verification accuracy. Then, the clamping head 501 is rotated, causing the screw 5 to spiral within the fixed seat 2. The clamping head 501 then presses against the movable seat 4 and moves downwards. Simultaneously, the movable column 301 moves downwards within the support column 3, compressing the clamping spring 302, thus moving the optical system downwards. Reversing the rotation of the screw 5 loosens the clamping head 501. The spring 302 rebounds and pushes the movable column 301 to move the movable seat 4 upward, realizing the upward movement of the optical system. This allows the optical system to be adjusted vertically according to the actual situation. Then, the beam generated by the optical system passes through the front target ring 9 and the rear target ring 10 in sequence. After being blocked by the combination of the longitudinal baffle 901 and the transverse baffle 1001, it forms a cross shadow on the surface of the imaging plate 11, which matches the shape of the beam groove 1101. After the beam passes through the circular through holes of the longitudinal baffle 901 and the transverse baffle 1001, it forms a coincident circular light spot in the center of the beam groove 1101. Then, it is approved as qualified. The result is clear at a glance. Combined imaging effectively avoids the error caused by visual inspection.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
