CVD ZnSe Main Properties: The transmission range is 0.5 μm - 22 μm. Used for high power CO2-laser optics at 10.6 microns.
Single crystal ZnSe is available for lower absorption and thus more effective for CO2 optics，Used for Optical prisms, lenses, wedges, windows, other optical components, and etc |

Used as windows of thermal imaging system. There are two specifications of CVDZnS, standard ZnS works at the transmittance range of Mid-infrared ( 3-5um ) and Far-infrared (8-12um ), while ZnS after hot isolate press (HIP) treated also can work at the transmittance range of visible band. |

our optical glass supplier is CDGM, Schott, Ohara, Dansil, and none specifical glass for us. but we usually suggest using china material instead of foreign glass. |
