Abstract

The invention relates to the technical field of lens processing, and provides an optical lens processing method, which is used for processing the optical lens and comprises the following steps of 1, determining processing data of the optical lens, 2, according to the processing data of the optical lens, roughly grinding the optical lens through a spherical surface milling and grinding machine, andreserving allowance, and 3, fixing the optical lens subjected to rough grinding to a clamping jig, and using a ball head cutter for conducting accurate grinding on the optical lens. The invention also provides an optical lens and a laser field lens. According to the optical lens processing method, the efficiency and precision requirements of a subsequent polishing process and an edge cutting process can be effectively improved, the surface roughness, curvature radius precision and concentricity of the optical lens processed through the method are greatly improved, and a laser field lens adopting the optical lens is high in laser transmittance.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to an optical lens processing method, an optical lens and a laser field lens. Background technique [0002] A laser scanning system is mainly composed of XY scanning mirror, field mirror, marking control system and software. A beam of laser light is reflected by the XY scanning mirror, then passes through the field mirror, and finally forms an image on the working surface. The quality of the field lens has an important influence on the imaging quality of the whole scanning system. Therefore, there is an increasing demand for field lenses, especially field lenses with a large scanning range and high imaging quality. Some existing field lenses with large scanning ranges have insufficient flat-field effects and relatively large geometric distortions. There are also some field lenses whose coaxiality is not good enough, and the laser focusing performance is poor. [0003] Th...
