Optical Colored Filter Glass is a glass material used to manufacture lenses, prisms, mirrors, windows, and other components for optical instruments or mechanical systems. It includes colorless optical glass (commonly referred to as optical glass), Optical Colored filter glass, radiation-resistant optical glass, radiation-shielding glass, and optical quartz glass.
Subei Optics specializes in Optical Colored Filter Glass,Coating Filter Glass,and Transparent Glass Windiow.
Dust-Free Environment
High-precision coating (e.g., for optical or semiconductor applications) is recommended to be performed in a Class 1000 cleanroom to minimize dust contamination risks and reduce the probability of pinholes or delamination caused by dust adhesion. Thorough cleaning of the vacuum chamber, substrate holders, and transfer equipment is required before and after coating to prevent contamination from residual impurities.
Temperature, Humidity, and Ventilation
Temperature should be maintained at 22±2°C, with humidity ≤45%. Elevated temperatures accelerate film oxidation, while excessive humidity promotes moisture adsorption, leading to haze formation or reduced adhesion. The vacuum chamber must be equipped with a dry gas (e.g., nitrogen) purge system to prevent residual moisture during thawing.
