Zinc Selenide Window (ZnSe) Dia. 50 mm x Thk. 3 mm, Uncoated FAQs

Q1: What are the key material properties of Zinc Selenide Window (ZnSe) Dia. 50 mm x Thk. 3 mm, Uncoated ?

A1: Zinc Selenide (ZnSe) is valued for a wide transmission range from approximately 0.6 µm to 20 µm, making it excellent for mid- and far-infrared applications. It has a relatively high refractive index of around 2.4 at 10.6 µm and offers exceptionally low absorption in the IR region. With a density of about 5.27 g/cm³, ZnSe is moderately hard, yet still prone to scratches and thermal shock if not handled carefully.

Q2: How should this product be handled and stored?

A2: Due to ZnSe's relative softness, store the uncoated window in a clean, dust-free container with protective padding to avoid surface scratches. When cleaning, use only non-abrasive materials and optical-grade solvents or deionised water. Avoid applying excessive force or contacting the lens with harsh chemicals. Handle the window by its edges, using lint-free gloves or finger cots, to prevent contamination and accidental damage.

Q3: Which quality standards and certifications apply to Zinc Selenide Window (ZnSe) Dia. 50 mm x Thk. 3 mm, Uncoated ?

A3: Most ZnSe windows are produced under ISO 9001-certified quality management systems to ensure consistent material purity and dimensional accuracy. They often comply with ISO 10110 specifications, detailing surface quality, wavefront distortion, and tolerance requirements. Additional standards, such as MIL-PRF-13830B, may be used to evaluate surface imperfections. These certifications help verify scratch-dig ratings, uniformity, and overall performance, guaranteeing that the product meets optical and mechanical quality criteria.
