Cutting method of optical element

Abstract

A method for cutting optical element includes such steps as providing a bench, fixing an optical element to be cut onto the bench, cutting it to a predefined deepth, turning over the optical element, fixing it onto the bench, and cutting the residual tickness.

Description

【Technical field】 [0001] The invention relates to a cutting method of an optical element, in particular to a cutting method of an optical element with a fine cutting surface. 【Background technique】 [0002] Cutting is a common process. With the advancement of technology, the requirements for the cutting end face after cutting are getting higher and higher. For optical components, their end faces need to have good precision to reduce the loss of light during transmission, that is, the end faces of optical components should have good finish, flatness and uniformity. [0003] In the prior art, knives are often used to cut optical components, because the surface shear force of the knives is different during the cutting process, and surface roughness such as chipping and edge chipping is likely to occur on the cutting surface, which has a great impact on the quality of optical components. In order to eliminate the surface roughness, additional processing, such as grinding and po...
