ZnSe Window

ZnSe laser lens is well-suited for optical elements in high-resolution thermal imaging equipment. ZnSe also transmits some visible light, unlike Germanium and silicon, thereby allowing for visual optical alignment. However, zinc selenide window is quite soft and will scratch easily. ZnSe window has an index of refraction of 2.403 at 10.6 µm.

Znse Laser Lens Features

Zinc Selenide windows are the best choice for a variety of IR applications and high-power CO2 laser systems. ZnSe has low IR absorption and high resistance to thermal application area. Zinc Selenide windows are best for thermal imaging. Zinc selenide windows are used in infrared imaging applications in scientific, military or search and rescue applications.ZnSe has a high index of refraction which requires an anti-reflection coating to achieve high transmission.ZnSe has good transmission from 3um-12um.Long wavelength transparency is crucial for imaging room temperature objects, which radiate at a peak wavelengths of approximately 10 µm with very low intensity.

ZnSe Windows Handling and Cleaning

ZnSe is very soft material, so we should very careful about it. It requests professional people to make it clean. It is also a toxic material. Great care must be taken in handling and cleaning the material. Wear gloves at all times to avoid the risk of contamination. Hold only the edge to prevent scratches. Wash hands after use. when holding the optics by its edges. wipe the surface gently with a damp cotton ball. Do not rub, and do not exert pressure. use only surgical quality cotton balls.
