Description

Technical Field

[0001] The invention belongs to the technical field of reflectors, and in particular relates to an optical reflector. Background Art

[0002] Silicon carbide is particularly suitable for applications in space optical systems due to its low thermal deformation, high specific stiffness, dimensional stability and radiation resistance. Silicon carbide reflectors are optical reflectors made of silicon carbide. They have good mechanical and physical properties and are suitable for optical system reflectors in space satellites, lidar systems and space telescopes.

[0003] In optoelectronic instruments, reflectors must be highly resistant to external dynamic interference, preventing displacement or deformation caused by external forces. This ability depends primarily on a fixed support structure. While effectively positioning the reflector, the fixed support structure must also minimize external interference and its effects on the reflector's surface shape. Consequently, there is a need to develop an optical reflector that can effectively resist deformation caused by environmental factors. Summary of the Invention

[0007] The outer layer is provided with an Invar sleeve, wherein an elastic bracket is provided inside the elastic connecting column, and a mounting plate is provided at one end of the elastic connecting column away from the Invar sleeve.

[0008] As a further improvement of the technology of the present invention, the elastic brackets are staggered on the inner wall of the elastic connecting column, and each bracket has multiple contact support points with the inner wall of the elastic connecting column.

[0009] As a further improvement of the technology of the present invention, the elastic bracket is fixed to the inner wall of the elastic connecting column by welding.

[0010] As a further improvement of the technology of the present invention, the elastic bracket and the elastic connecting column are both made of Ti alloy material.

[0011] As a further improvement of the technology of the present invention, the Invar sleeve, the spring steel sleeve and the elastic connecting column are fixed by screws.
