Abstract

The invention particularly relates to a flexible supporting structure for an ultralow-temperature infrared optical reflecting prism, and aims to solve the problem that the imaging quality is directly influenced by severe deformation of an optical reflecting mirror caused by large temperature difference between processing and assembling and actual working environments. The flexible supporting structure comprises a reflecting mirror base, a reflecting mirror end cover and a rubber block, wherein the reflecting mirror base is in an L shape, one side of the reflecting mirror end cover is fixedly connected with the other end of a base side support, the other side of the reflecting mirror end cover extends outwards and is kept parallel to the base of the base, the extension part is provided with the rubber block, a mounting area of the reflecting prism is formed among the rubber block, a flexible joint and the base side support, one end of the reflecting prism is connected with the flexible joint, the other end of the reflecting prism is connected with the rubber block, and the side part of the reflecting prism is connected with a vertical side beam.

Description

technical field [0001] The invention relates to a supporting structure of an infrared cold optical reflecting prism, in particular to a flexible supporting structure of an ultra-low temperature infrared optical reflecting prism. Background technique [0002] With the increasing demand for infrared detection, infrared cold optics technology has developed rapidly, and the low-temperature deformation of infrared optical components is one of the key factors restricting the development of infrared cold optics technology. In order to reduce the volume and weight of infrared optical components, the application of reflectors in the optical system is essential. In order to meet the refraction requirements of the optical system, strip mirrors are widely used. In the cold optical environment, the strip mirror shrinks and deforms more violently than other mirrors. The shrinkage deformation of the reflector is manifested in its own shrinkage on the one hand, and the relative deformatio...
