Cleaning method of coated lens

Abstract

The invention discloses a cleaning method of a coated lens. The cleaning method comprises the following steps: performing ultraviolet light activating treatment on the coated lens, performing further activation with an activation reagent, rinsing with a cleaning agent, rinsing with pure water, performing slow pulling in pure water and drying in a drying oven filled with a dionized gas. The cleaning method of the coated lens can solve the problem in the prior art that with the conventional cleaning process, particulate matters and watermarks on the surface of a lens cannot be eliminated, the product quality and qualification rate are greatly improved, the production cost of coated optical devices is reduced considerably, the production efficiency is highly improved and the adaptation to market production and economic needs is facilitated.

Description

technical field [0001] The invention belongs to the field of optical instrument production, in particular to a method for cleaning coated lenses. Background technique [0002] Due to continuous innovation in optical technology and engineering, the development of new products is changing with each passing day. Cleaning is an indispensable quality and quality assurance in this field. Due to the increasing complexity and quality requirements of the processing links, the current traditional cleaning process often cannot meet the requirements of the latest technology and engineering processes. The main problem is that the extremely fine particles and watermarks attached to the surface of the lens are often difficult to completely remove. For different lens situations, the cleaning methods are often quite different. Our company has developed a new type of optical coating device, but there is a lack of corresponding cleaning agents and cleaning processes in the core manufacturing...
