Abstract

The invention discloses an aspheric-surface optical device polishing process and belongs to the field of optical component processing. The aspheric-surface optical device polishing process comprises the following implementation process that magnetorheological fluid and a magnetic field are arranged; the magnetorheological fluid forms an annular polishing tool under the action of the magnetic field; and the annular polishing tool and a processing workpiece to be polished are in contact to generate relative motion, so that the processing surface to be polished is polished. According to the aspheric-surface optical device polishing process, the surface of an aspheric-surface optical device can be polished.

Description

technical field [0001] The invention relates to the field of processing optical components, in particular to the polishing process of aspheric optical components. Background technique [0002] With the rapid development of today's society, people's living standards continue to improve, smart phones, driverless cars, military infrared equipment, medical endoscopes and security video surveillance and other fields are in the ascendant, optical components are the core devices in these fields, in There will be a broader market prospect in the future. [0003] Traditional optical components use spherical optical components. After the light passes through the spherical mirror, the focal point of the light diverges and the image is blurred, which will cause certain errors in the accuracy of the image information. In recent years, people have gradually begun to use aspheric optical components to replace traditional spherical optical components. Aspheric optical components can elimin...
