Abstract

The invention relates to a method for polishing the surface of an optical lens. The method includes the steps that S1, materials are arranged in working solutions added with suspension abrasives; S2,the working solutions are heated to a preset temperature and kept constant; and S3, ultrasonic vibration is applied to the working solutions to polish the surfaces of the materials. The method for polishing the surface of the optical lens can effectively solve the problem of poor surface finish caused by mildewing and misting due to turnover process contamination and excessive storage time after surface mirror finishing is conducted on an infrared optical material lens.

Description

technical field [0001] The invention relates to a polishing method, in particular to a polishing method for the surface of an optical lens. Background technique [0002] Infrared optical lenses have a wide infrared transmission window, from the visible light band to 14μm, and have a low temperature coefficient of refraction index and dispersion coefficient. This makes infrared glass an ideal material for correcting chromatic aberration and avoiding thermal defocusing phenomena in infrared optical lenses. [0003] However, due to the characteristics of infrared optical materials, the surface of the lens is easily polluted and fogged, and cannot be removed by conventional wiping or ultrasonic cleaning, which affects the quality of the coating surface. Chinese patent 201710983186.0 discloses a method of cleaning lenses using ultrasonic waves. Although this method can clean off the residue attached to the surface of the lens, it cannot solve the problem of contamination in the ...
