Anti-Reflection Coatings

Anti-reflection (AR) coating is a solution to reduce glass glare and reflection, and enhancing the transmission of visible light.
We supply single side and double side AR coating. With single side coating, except for being an economical option, it can be an enhancer of certain filter as well. For example adding AR coating on UV cut filter to improve the transmission of visible light, or on a beam splitter to avoid Fresnel reflection.
With double side AR coating, it maximizes the performance of AR coating with average transmission rate over 98%.
