The ZNW15AR.20 is a 3 µm to 12 µm antireflection coated, 40.00 mm in diameter and 4.00 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.
