ZnSe Windows

ZnSe is an infrared optical material with a remarkably wide transmission wavelength range from visible to mid-infrared (0.45 µm to 21.5 µm) and thus is ideal for a wide variety of infrared applications including CO2 laser optics, thermal imaging, and medical systems. The good transmission at 632nm makes it possible to use a HeNe laser for alignment in an IR system.

Newlight Photpnics offers uncoated parallel ZnSe windows. Windows with a wedge angle are available upon request.
