Zinc Sulfide Window (ZnS) Circular, Uncoated FAQs

Q1: What are the key material properties of Zinc Sulfide Window (ZnS) Circular, Uncoated ?

A1: Zinc Sulfide (ZnS) is a polycrystalline infrared material that offers excellent optical transparency in the 3 to 12 µm range. It has high chemical and thermal stability, making it suitable for harsh environments. ZnS has a relatively low refractive index, reducing reflection losses. Moreover, it possesses moderate hardness and strength, providing a balance between durability and ease of fabrication for various optical applications.

Q2: How should this product be handled and stored?

A2: Zinc Sulfide windows should be handled with clean, lint-free gloves to prevent surface contamination and scratches. They are moderately brittle, so avoid exerting uneven pressure or dropping them. Store these optics in protective, padded containers with minimal humidity and temperature fluctuations. When cleaning, use gentle methods such as solvent-soaked, non-abrasive wipes, and avoid harsh chemicals or ultrasonic cleaners that could damage the surface.

Q3: Which quality standards and certifications apply to Zinc Sulfide Window (ZnS) Circular, Uncoated ?

A3: Zinc Sulfide windows generally conform to stringent optical specifications defined by standards such as MIL-PRF-13830B for surface quality, ISO 10110 for optical tolerances, and ASTM E903 for transmittance measurements. Manufacturers often ensure consistent refractive index and verify minimal inclusions or defects. These windows may also undergo environmental testing, such as thermal cycling and humidity exposure, to ensure reliable performance under demanding conditions.
