Material
Exit windows made of tempered glass or plastic can be AR coated. The AR coated glass
features better adhesion. What’s more, putting AR coating on the glass is more cost-effective.
Anti-reflection Coating
Single side: the minimum transmittance is 92% within spectrum range from 420 nm to 730 nm.
Double side: the minimum transmittance is 97% within spectrum range from 420 nm to 730 nm.
