Durable, Front Surface Hard Optical Coatings for Replacing Laminated Soft Coatings

Download Whitepaper
Soft coatings possess poor environmental durability, poor temperature stability and low transmission, high optical scatter, yet they are still used mostly due to low cost. Alluxa’s advanced high speed deposition technology has finally enabled hard coatings to compete on price with soft coatings, even in small batch sizes. Alluxa’s filters offer dramatically improved transmission, spectral shape, and lifetime.
