Product Description

General Introduction: Raytek ZnSe window is an ideal choice for various infrared applications including high power CO2 laser system. ZnSe has low infrared absorption and high thermal shock resistance. However, due to the softness of the material, the window must be handled with care.

Products Name: Zinc Selenide Optical Windows
Alias: Zinc Selenide Optical Windows, Zinc Selenide Windows, Zinc Selenide Optics Windows, Zinc Selenide Laser window, ZnSe Optical windows, ZnSe Parallel Windows, Zinc Selenide Infrared Window, Zinc Selenide IR window, ZnSe Infrared Lens, ZnSe Laser lens, ZnSe Optical lens, Zinc Selenide Optical Lens, etc

Lens Substrates:
Zinc Selenide (ZnSe)
 

Optional I:	Zinc Selenide (ZnSe) from CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETC
Optional II:	Equivalent Zinc Selenide (ZnSe) Made in China, C-laser own brands

Coating:
3 to 12μ m Broadband coating
ZnSe has high refractive index, so it needs to be coated with antireflective film to achieve high transmittance. Our broadband AR.20 coating is optimized for 3 to 12μM

Main Applying:

Applying Fields I:	High power CO2 laser system. Infrared thermal imaging equipment
Applying Fields II:	Infrared imaging applications in scientific, study or search and rescue applications.
