Equipment for manufacturing aspheric mirror and application thereof

Abstract

The invention discloses equipment for manufacturing an aspheric mirror. The equipment comprises a body, a film, an accommodating container and a pressure controller, wherein the body is provided with a first cavity and a through hole, the film covers the through hole, and the pressure controller adjusts the pressure of the first cavity. The invention also discloses a manufacturing method of the aspheric mirror. The method comprises the following steps: providing the equipment; acquiring the required pressure; adjusting the pressure of a first cavity; pouring a curing adhesive into an accommodating container; and curing. The invention further discloses a manufacturing method of a double-sided aspheric mirror, wherein two aspheric lenses are manufactured through the method, and are attached to each other. The invention further discloses a manufacturing method of an aspheric reflector. The method comprises: preparing an aspheric mirror through the method, and preparing a metal film on the surface of the aspheric mirror. According to the invention, the pressure controller is used for adjusting the pressure difference between the first cavity and the outside so as to control the deformation of the needed morphology of the film, so that the curing adhesive poured into the accommodating container is correspondingly deformed, and the aspherical mirror with any surface morphology and high precision is obtained after curing.

Description

technical field [0001] The invention relates to the technical field of aspheric mirrors, in particular to a device for making aspheric mirrors and its application. Background technique [0002] In the optical system, the aspheric surface can simplify the structural organization of the instrument, help to correct spherical aberration, and improve image quality. However, the reason why aspheric lenses have not been adopted in a large area so far is also because the processing technology of aspheric parts has not reached a mature stage. [0003] There are many reasons for the complexity of aspheric surface processing. The more obvious reason is that most of the aspheric surfaces have only one symmetry axis. At the same time, the curvature of each point of the aspheric surface is also different; Insufficient and problems such as cracks and bubbles in the lens during the production process. Therefore, limited by many aspects, it is difficult to realize the manufacture and mass ...

[0003] There are many reasons for the complexity of aspheric surface processing. The more obvious reason is that most aspheric surfaces have only one symmetry axis. At the same time, the curvature of each point of the aspheric surface is also different; Insufficient and problems such as cracks and bubbles in the lens during the production process

Therefore, limited by these many aspects, it is difficult to realize the production and mass production of aspheric mirrors with any surface morphology.
