ZnSe

ZnSe is a kind of yellow and transparent mulit-cystal material, the size of crystalline particle is about 70um, transmitting range is from 0.5-15um. Znse material made by chemical vapor deposition(CVD) basically doesn’t exist impurity absorption, scattering damage is very low. Because of a very low light absorption for 10.6um wavelength, so ZnSe is the first choice material for making optical elements of high-power Co2 laser system. Furthermore ZnSe is also a kind of common used material for different optical system in whole transmitting waveband.

Applications:

  • High and low power laser, 

  • laser system, 

  • medical science,

  • astronomy and IR night vision.

Features:Low scattering damage.
