Abstract

The invention discloses a cleaning processing method of the surface of a large-diameter precise optical element. The method comprises the following steps of element offline, removal of residual polishing powder and solid stains on the edge, washing with 15-M deionized water for 3 minutes, 270-KHZ ultrasonic cleaning for 2 minutes, superior pure alcohol replacement, alcohol dehydration and wiping.The cleaning processing method of the surface of the large-diameter precise optical element has the advantages that the residual polishing powder and solid substances on the surface of the element canbe thoroughly removed, the deionized water and ultrasonic waves are utilized to clean the surface of the element rapidly, and then a method of fast dehydration with superior pure alcohol is used, sothat the stains on the surface of the element after the element is processed are thoroughly removed, and the 50-level cleaning requirement of the element surface is achieved.

Description

technical field [0001] The invention relates to precision manufacturing of non-metallic materials, mainly used in the technical field of ultra-strong, ultra-short, and high-power lasers, and in particular to a method for cleaning the surface of large-diameter precision optical elements. Background technique [0002] Due to the characteristics of the material, the surface of large-aperture optical components is prone to deliquescence. According to the conventional experience of precision cleaning treatment of components, the best way to clean the surface of components is to use water cleaning. Organic solvents cannot completely remove the residual polishing powder and solids on the surface of components. physical. For this reason, a water agent is designed to quickly clean the surface of the component, and then use high-grade pure alcohol to quickly dehydrate the surface to completely remove the dirt on the surface of the component after processing, and to achieve the cleanli...
