Industry & Occupation
Classification
Summary
Specialized occupation that applies thin-film coatings such as anti-reflective and anti-fouling films to the surface of optical lenses to enhance functionality and durability.
Description
Coat processing worker (lens manufacturing) is an occupation that applies anti-reflective films, anti-fouling films, hard coat films, etc., to the surface of optical lenses. After cleaning the lens material, it is loaded into a vacuum evaporation device or sputtering device, and uniform thin films are formed while adjusting film formation conditions such as evaporation rate, temperature, and pressure. After film formation, the uniformity and performance of the coating are inspected using a film thickness meter or spectrophotometer, and qualified products are shipped. Duties also include process improvements, analysis of causes of quality defects, and equipment maintenance.
Future Outlook
With the growth of the optical equipment market, demand for thin-film coatings is expanding. Technological innovations are expected in high-performance lens fields for automotive LiDAR and AR/VR.
