Zinc Sulfide Window (ZnS) Dia. 25.4 mm x Thk. 3.0 mm, AR Coating FAQs

Q1: What are the key material properties of Zinc Sulfide Window (ZnS) Dia. 25.4 mm x Thk. 3.0 mm, AR Coating?

A1: Zinc Sulfide (ZnS) is an infrared-transmitting material with a high refractive index of around 2.2, excellent optical clarity from visible to mid-infrared wavelengths, and moderate hardness of approximately 120 Knoop. With a diameter of 25.4 mm and thickness of 3.0 mm, this window is typically coated with an anti-reflective layer to enhance transmission efficiency and reduce scattering. It also offers thermal shock resistance, making it suitable for environments.

Q2: How should this product be handled and stored?

A2: Dust-free gloves should be worn at all times, and only approved lens cloths or non-abrasive tissues should come into contact with the coated surface. The window should be carefully secured during installation to avoid stress, and it must be stored in a clean, low-humidity environment. Contaminants or mishandling can degrade the anti-reflective coating and compromise performance.

Q3: Which quality standards and certifications apply to Zinc Sulfide Window (ZnS) Dia. 25.4 mm x Thk. 3.0 mm, AR Coating?

A3: Zinc Sulfide (ZnS) optical windows typically adhere to ISO 10110 specifications for surface quality, roughness, and wavefront distortion, ensuring minimal scattering and high transmission. Many manufacturers comply with MIL-PRF-13830B standards to guarantee performance, scratch-dig tolerances, and coating durability. Testing may also follow MIL-STD-810 requirements for robustness, confirming resistance to temperature extremes, humidity, and shock to meet defence and industrial needs.
