Support device for optical lens

Abstract

The invention provides a support device for an optical lens and relates to the technical field of the manufacture, installation and adjustment of the optical lens. The device comprises a lens framework, a hollow bolt, an adhesive, an optical lens pressing block and a connection bolt. The optical lens is arranged in the lens framework; the radial position of the optical lens in the lens framework is adjusted by the hollow bolt; the axial location is realized through the optical lens pressing block and the connection bolt; and the radical location is realized by injecting adhesive in from an adhesive injecting hole in the hollow bolt. The support structure provided by the invention is simple and easy to process and manufacture, can effectively guarantee the location precision and the surface type precision of the optical lens and is convenient for the disassembly of the optical lens. The support device of the optics lens can be widely applied to optical engineering and optical experimental devices and has strong practical applicability.

Description

technical field [0001] The invention relates to the technical field of optical lens manufacture and assembly, in particular to a frame structure supported by optical lenses. Background technique [0002] The manufacture and assembly of optical lenses is a very precise process. With the improvement of optical design level, in order to achieve high-quality imaging performance and obtain higher resolution, optical lenses are required to ensure micron-level positioning accuracy and maintain RMS value nano-level surface accuracy, but the existing The supporting structure of optical lenses is either difficult to meet the requirements at the same time, or the structure is complex and difficult to process. [0003] Adhesives of various types are often used in place of screws, rivets and other forms of fasteners in the design and production of modern optical instruments. Compared with the mechanical fastening method, the adhesive will make the distribution of stress more uniform, e...

AI Technical Summary

Problems solved by technology

Compared with the mechanical fastening method, the adhesive will make the distribution of stress more uniform, especially for compensating the influence of temperature change and adjustment force on the surface accuracy of the optical lens. The frame is tightly bound and difficult to remove

For high-precision optical lenses, optical lenses often need to be repeatedly processed, coated, and adjusted, which requires the optical lenses to be taken out of the frame many times, and the existing optical lens support structure, the optical lens fastened by adhesive It is difficult to take out, and it is easy to scratch the optical lens in the process of taking it out
