Zinc Selenide Window (ZnSe) Dia. 101.6 mm x Thk. 6 mm, Uncoated FAQs

Q1: What are the key material properties of Zinc Selenide Window (ZnSe) Dia. 101.6 mm x Thk. 6 mm, Uncoated?

A1: Zinc Selenide offers broad spectral transmission from about 0.5 µm to 15 µm, making it suitable for mid-IR systems. Its refractive index (~2.4 at 10.6 µm) and low dispersion contribute to excellent beam quality. The material has a Knoop hardness of ~120 and a density of 5.27 g/cm³. It also exhibits a thermal expansion coefficient of approximately 7.1×10⁻⁶/°C.

Q2: How should this product be handled and stored?

A2: Because Zinc Selenide is relatively soft and prone to scratches, it’s essential to handle it only with gloved hands or use soft, lint-free cloth to avoid damage. Avoid contacting the polished surfaces with bare fingers or contaminated tools. Store the window in a clean, dry environment at stable temperatures to prevent moisture or thermal shocks. Use protective containers with foam padding to shield it from vibration.

Q3: Which quality standards and certifications apply to Zinc Selenide Window (ZnSe) Dia. 101.6 mm x Thk. 6 mm, Uncoated?

A3: These windows are commonly manufactured under rigorous quality control processes aligned with ISO 9001 guidelines to ensure consistent optical performance and dimensional accuracy. Optical tolerances may also adhere to ISO 10110 specifications, covering aspects like surface quality and irregularity. Many suppliers conduct in-house testing for transmission, scattering, and surface imperfections, and some products hold RoHS compliance. Certification documents typically accompany the delivered windows for full traceability.
