ZnSe Windows
Zinc Selenide (ZnSe) is a preferred material for IR windows for its low absorptivity at infrared
wavelength and its visible transmission.
Creator optics (CNCO) supply high quality ZnSe windows with custom size. All of these custom
made ZnSe windows are desighed to be used in precision optical, CO2 laser and Infrared
systems.
The circumference is fine ground and both edges are no-chips beveled.
