Specification
Description
Material
Both tempered glass and plastic (for example, CR-39 or hard coated acrylic) exit windows can be AR coated. AR coated glass is easier and more durable because of a better adhesion property on the glass structure. In addition, it can be more cost effective to put an AR coating on the glass substrate rather than on the plastic.
AR Coating Specification
  • Single side AR-coating: 92% minimum transmittance within spectrum range from 400 nm to 900 nm.
  • Double side AR-coating: 97% minimum transmittance within spectrum range from 400 nm to 900 nm.
