Zinc Selenide Window (ZnSe) Dia. 30 mm x Thk. 3 mm, Uncoated FAQs
Q1: What are the key material properties of Zinc Selenide Window (ZnSe) Dia. 30 mm x Thk. 3 mm, Uncoated?
A1: Zinc Selenide (ZnSe) is a chemically vapour-deposited material with a broad transmission range from approximately 0.5 µm to 22 µm, making it ideal for infrared applications. It has a relatively low refractive index of around 2.4 at 10.6 µm and offers good thermal shock resistance. The Knoop hardness is typically around 120, indicating a softer material that requires gentle handling to avoid scratches. Its excellent optical uniformity ensures minimal distortion in imaging or beam delivery systems.
Q2: How should this product be handled and stored?
A2: Due to its somewhat soft nature, ZnSe windows should be handled with nitrile or powder-free gloves to protect surfaces from oils and scratches. When cleaning, use optical-grade wipes and approved solvents, avoiding abrasive materials. Store the window in a closed container or sealed bag with desiccant in a clean, dry environment to prevent contamination. Inspect surfaces regularly, and avoid any contact with corrosive substances or sudden temperature changes.
Q3: Which quality standards and certifications apply to Zinc Selenide Window (ZnSe) Dia. 30 mm x Thk. 3 mm, Uncoated?
A3: These ZnSe windows are typically produced and tested under ISO 9001-certified management systems to ensure consistent manufacturing quality and traceability. Optical surface specifications may meet or exceed ISO 10110 or MIL-PRF-13830 standards, which define allowable surface imperfections and wavefront requirements. Additionally, they may comply with RoHS directives for restricted hazardous substances and are subject to thorough metrology checks for diameter, thickness tolerance, and transmitted wavefront performance.
