• Ideal for high power CO2 laser applications

• Extremely low IR absorption

• Highly resistant to thermal shock

• 3 to 12 µm broadband IR antireflection coating

• Soft material not recommended for harsh environments

• Low dispersion and low absorption coefficient

Zinc Selenide windows are an excellent choice for a variety of IR applications including high power CO2 laser systems. Zinc Selenide offers low IR absorption, and high resistance to thermal shock. However, windows must be handled with caution due to material\'s softness.

Features

Ideal for Thermal Imaging

Zinc Selenide has low IR absorption, and is transparent across a very wide 0.6-16 µm spectral range. This is advantageous for thermal imaging, where temperatures of remote objects are ascertained via their blackbody radiation spectrum. Long wavelength transparency is crucial for imaging room temperature objects, which radiate at peak wavelength of approxiamtely 10 µm with very low intensity.

3 to12 µm Broadband Coating

ZnSe has a high index of refraction which requires an anti-reflection coating to achieve high transmission. Our broadband AR.20 coating is optimized for 3 µm to 12 µm.

Withstands Thermally Demanding Environments

Zinc Selenide windows are ideally suited for thermally demanding environments. The windows are both low in absorption and high in thermal shock making them usable even in high power CO2 laser applications. These windows may also be used in applications such as IR imaging in scientific, military, or search and rescue applications.

Handle With Caution

Zinc Selenide material formed to with extremely high purity by molecular beam epitaxy. Zinc selenide is a soft material, making it resiliant and tolerant of thermal shock. However, this means that great care must be taken in handling and cleaning the material to prevent scratches. Zinc Selenide should handled only by the edges. Rubber gloves should be worn at all times as Zinc Selenide is toxic.
