Zinc Selenide Window (ZnSe) Dia. 40 mm x Thk. 4 mm, Uncoated FAQs

Q1: What are the key material properties of Zinc Selenide Window (ZnSe) Dia. 40 mm x Thk. 4 mm, Uncoated?

A1: Zinc Selenide is renowned for its low absorption in the infrared spectrum, making it ideal for CO₂ laser applications and other IR optical systems. It exhibits a refractive index of approximately 2.4 at 10.6 µm and maintains high optical transmittance from about 0.5 µm to 22 µm. With a relatively soft surface, ZnSe is vulnerable to scratches and requires careful handling. In addition, its thermal conductivity and fracture toughness allow efficient performance under moderate temperature and mechanical stress conditions.

Q2: How should this product be handled and stored?

A2: Due to Zinc Selenide’s soft nature and susceptibility to scratches, it is crucial to handle it with clean, lint-free gloves and avoid direct contact with hard surfaces or dust. Store the window in a cushioned container with protective padding to reduce the risk of chipping and contamination. Prior to usage, gently clean with a recommended solution or solvent, ensuring no harsh chemicals are applied and avoiding excessive force that could damage the optical surface.

Q3: Which quality standards and certifications apply to Zinc Selenide Window (ZnSe) Dia. 40 mm x Thk. 4 mm, Uncoated?

A3: Quality standards for ZnSe windows typically include strict adherence to ISO specifications for optical tolerances, surface quality, and environmental safety. Manufacturers often certify their products under ISO 9001 for quality management, while some also comply with RoHS directives to ensure minimal hazardous substance usage. In addition, many suppliers conduct thorough in-house inspections for dimensional accuracy, surface finish, and laser damage thresholds to meet both industry specifications and customer requirements.
