AR (Anti Reflection) coating is a type of coating to suppress surface reflection of lenses, etc. The main coating method is by vapor deposition, which is a dry process. We offer AR coating by wet dip-coating.
Advantages of the dip-coating method include the following
-
Mass production
-
Reduced equipment cost
-
Small-lot production possible
-
Higher work efficiency compared to vapor deposition coating
-
Compatible with multilayer films
-
Support for complex shapes
Large-diameter glass tube outer and inner circumference, lens arrays (proven track record)
