Technical Field

[0001] This utility model relates to the field of secondary mirror support equipment technology, and in particular to a triangular support ring for supporting secondary mirrors. Background Technology

[0002] In the field of space cameras today, reflective optical systems are being used more and more widely. However, space cameras often operate in harsh environments with wide ranges of thermal variations, and stray light in space can also affect the image quality. For reflective optical systems, the relative positions of the primary and secondary mirrors directly affect the camera's functionality.

[0003] Currently, similar products on the market can all provide connection and support, but they generally suffer from insufficient stability of the support structure. The support structure is prone to plastic deformation during experiments, making it difficult to achieve stable support, which affects the stability of the secondary mirror and thus the overall imaging effect.

[0004] Therefore, those skilled in the art have provided a triangular support ring for secondary mirror support to solve the problems mentioned in the background art. Utility Model Content

[0005] This utility model provides a triangular support ring for supporting a secondary mirror, which is simple in design, more stable in structure, and enables the secondary mirror to be more stable in the overall imaging effect, resulting in better overall imaging effect.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 As shown;

[0027] The triangular support ring for secondary mirror support described in this embodiment of the utility model includes:

[0028] A triangular secondary mirror support ring 1 is provided with a secondary mirror light shield 2 at the light-incident end of the triangular secondary mirror support ring 1; the triangular secondary mirror support ring 1 plays the role of overall support, light shielding and structural stability; the light shield 2 is used to shield stray light;

[0029] Secondary mirror 3, which is mounted on secondary mirror flexible joint 4, is located inside secondary mirror adjustment pad 5, and the secondary mirror flexible joint 4 and secondary mirror adjustment pad 5 are located inside secondary mirror light shield 2 and connected to triangular secondary mirror support ring 1.

[0030] The secondary mirror 3 and the secondary mirror flexible joint 4 are bonded together to form an integral structure for light emission; the secondary mirror adjustment pad 5 can fine-tune the secondary mirror 3.

[0031] The secondary mirror heat insulation pad 6 is installed on the light-incident end of the triangular secondary mirror support ring 1. The secondary mirror heat insulation pad 6 is located inside the secondary mirror light shield 2 and plays a role in heat insulation.

[0032] In practical use, the secondary mirror 3 is supported by the secondary mirror flexible joint 4, and the position of the secondary mirror 3 is adjusted by the secondary mirror adjustment pad 5 to avoid plastic deformation. This enables fine-tuning and stable support of the secondary mirror 3, thereby ensuring the overall imaging effect.

[0033] One end of the secondary mirror light shield 2 extends out of the triangular secondary mirror support ring 1, allowing light to enter the secondary mirror light shield 2. The other end of the secondary mirror light shield 2 is located inside the triangular secondary mirror support ring 1, allowing light to be transmitted to the secondary mirror 3 inside the secondary mirror light shield 2.

[0034] A first protrusion 7 protrudes outward from the middle of the end face of the secondary mirror 3 near the secondary mirror joint 4, and the first protrusion 7 extends into the secondary mirror joint 4. A first through hole 8 is provided in the middle of the secondary mirror joint 4, and an annular protrusion 9 protrudes outward from the end face of the secondary mirror adjustment pad 5 near the first through hole 8, and the first protrusion 7 extends into the first through hole 8 and the annular protrusion 9.

[0035] The secondary mirror 3 and the secondary mirror flexible joint 4 are bonded together to form an integral structure, and the secondary mirror flexible joint 4 provides stable support for the secondary mirror 3.

[0036] The secondary mirror adjustment pad 5 has a second through hole 10 in the middle, and the annular protrusion 9 passes through the second through hole 10.

[0037] The secondary mirror flexible joint 4 and the secondary mirror adjustment pad 5 are connected to the light-incident end of the triangular secondary mirror support ring 1 via a first hexagon socket screw. The first hexagon socket screw passes sequentially through the threaded holes 12 on the triangular secondary mirror support ring 1, the secondary mirror adjustment pad 5, and the secondary mirror flexible joint 4, so that the triangular secondary mirror support ring 1 can stably support the secondary mirror 3 through the secondary mirror flexible joint 4; the distance between the secondary mirror flexible joint 4 and the triangular secondary mirror support ring 1 can be adjusted by changing the thickness of the secondary mirror adjustment pad 5, thereby achieving the adjustment of the secondary mirror 3.

[0038] The secondary mirror heat insulation pad 6 has a third through hole 11 in the middle. The secondary mirror heat insulation pad 6, the secondary mirror adjustment pad 5 and the secondary mirror 3 are coaxially arranged. The secondary mirror heat insulation pad 6 is connected to the light-incident end of the triangular secondary mirror support ring 1 by the inner second hexagonal screw, which can make the secondary mirror heat insulation pad 6 stably set on the triangular secondary mirror support ring 1 and ensure the heat insulation effect.

[0039] In use, first determine the size of the secondary mirror 3 and the first protrusion 7, and then design the size of the connection point on the triangular support ring of this application. The triangular support ring changes with the structure of the secondary mirror so that this application can adapt to the varied secondary mirror structure.
