Antireflective Coatings
 

Anti-Reflection (AR) coating is one of widely used optical thin-film coatings that can be applied to the surfaces of optical elements to reduce reflection and to improve transmittance within some spectral region.
We provide AR coatings with appropriate materials and optimized configuration on a substrate material specified by the customer, with specified transmittance and a specified wavelength region.
