Optical Window, Zinc Selenide, 12.5 mm Diameter, 2.0 mm Thick, 3-12 µm

The ZNW11AR.20 is a 3 µm to 12 µm antireflection coated, 12.50 mm in diameter and 2.00 mm thick Zinc Selenide window. Zinc Selenide windows have wide variety of usage in high power CO₂ laser systems because of its low absorption coefficient and high resistance to thermal shock. It is an excellent choice for many MWIR (Mid-Wave Infrared) to IR applications due to its broad wavelength range.
