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
