Attention! You can customise this product to your needs.
Zinc Selenide is commonly used in thermal imaging, FLIR, and medical systems. It has wide usage in high power CO2 laser systems because of its low absorption coefficient and high resistance to thermal shock.

  • grows Zinc Selenide (ZnSe) CVD ingots with size up to 270 mm x 500 mm, thickness up to 20 mm, transparent during the spectral range (0.5-20) microns, of optical and laser grade.
  • manufactures the following Zinc Selenide (ZnSe) CVD optics:
    blanks, windows, protective windows, wedges, spherical and cylindrical lenses, meniscus, right angle prisms, ATR prisms, CO2 optics, resonator mirrors for CO2 laser, Brewster windows, spherical microlenses, balls and hemisphere, domes and witness samples
  • offers Evaporation Grade Zinc Selenide (size less than or equal to 6 mm, purity: 99.999%)

ZnSe CVD laser grade
(optical component dimensions 3-100 mm, thickness up to 20 mm, grain size 50-70 microns, Index of absorption ≤0.0005 cm-1 at 10.6 microns) is used in high power CO2 laser optics, in medical applications.

Spectral transmittance (
ԏ) of ZnSe laser grade uncoated polished window (thickness 2mm), range 2.5-20 microns. For visible range ԏ≥62% at 633 nm.

ZnSe
ZnSe CVD IR optical grade
(optical component dimensions 3-300 mm, thickness up to 20 mm, grain size 20-100 microns, Index of absorption ≤0.003 cm-1 at 10.6 microns) is used in protective windows and thermal imaging equipment, in Industrial applications.
