Both tempered glass and plastic windows can be AR coated. However, it is easier and more cost-effective to put an AR
coating on the glass than on the plastic.
The AR coating specifications below should be met when using an AR coated window.
Single side AR coating: 92% minimum transmittance within spectrum range from 420 nm to 730 nm.
Double side AR coating: 97% minimum transmittance within spectrum range from 420 nm to 730 nm.
