Abstract

The invention provides a lightweight, simplified, high-stability and coaxial camera primary and secondary lens assembly. The lightweight, simplified, high-stability and coaxial camera primary and secondary lens assembly comprises a bearing cylinder, and a primary lens component and a secondary lens component of a coaxial camera, and further comprises a metal insert, an insert supporting component and a plurality of radial supporting rods, wherein the bearing cylinder, the insert supporting component and the radial supporting rods are carbon fiber composite components; the insert supporting component adopts a circular ring structure, and is coaxially arranged in the center of a front flange of the bearing cylinder through the radial supporting rods; the metal insert is fixed inside the insert supporting component; the primary lens component is mounted at a back flange of the bearing cylinder; the secondary lens component is mounted inside the metal insert. Through a high-precision designing, machining and mounting method for the integrated primary and secondary lenses, a design of a metal flange plate in the conventional scheme is avoided, so that the weight is reduced to a half of that in the conventional scheme.

Description

technical field [0001] The invention patent relates to a primary and secondary mirror component and installation method for a coaxial camera, especially a high-precision installation and support method between the primary and secondary mirrors with high light weight, simplification, high modulus, and high stability. Background technique [0002] Many high-resolution cameras currently developed at home and abroad use small relative aperture and long focal length optical systems. This structural form of the optical system has the advantages of compact structure and excellent image quality. However, in this structural form of the optical system, slight deformation between the primary and secondary mirrors will affect the image quality of the camera. Carbon fiber composites are widely used in this type of camera as a support structure with high specific stiffness and high thermal stability between the primary and secondary mirrors. [0003] The amount of change in the back inte...
