An introduction on how to select infrared optical glass lenses

The visible light band ranges from 400 to 700 nanometers, which are the colors that the human eye can distinguish. The infrared glass in Xiamen is 532nm for green and 633nm for red, with a difference of 100nm between the two. Lenses used within this range have very high requirements for the peak value of the coating ce...
