Zinc Sulfide Window (ZnS) Dia. 50.8 mm x Thk. 3.0 mm, AR Coating FAQs

Q1: What are the key material properties of Zinc Sulfide Window (ZnS) Dia. 50.8 mm x Thk. 3.0 mm, AR Coating?

A1: Zinc Sulfide (ZnS) is an optical ceramic with good mechanical strength and excellent transmittance in the 0.4 to 12 µm range. The AR coating reduces surface reflections and enhances transmission efficiency. It has a refractive index around 2.2, moderate thermal expansion, and good thermal conductivity. The 50.8 mm diameter and 3.0 mm thickness provide stability for various optical setups, including imaging and spectroscopy applications.

Q2: How should this product be handled and stored to prevent damage to the AR coating?

A2: Due to Zinc Sulfide’s moderate hardness and the fragility of the AR coating, handle the window only with clean, powder-free gloves and avoid contact with rough or abrasive surfaces. Store the window in a clean, dry environment, preferably in a protective case with soft, lint-free padding to prevent scratches. Avoid exposure to extreme temperatures or sudden thermal shocks.

Q3: Which quality standards and certifications apply to Zinc Sulfide Window (ZnS) Dia. 50.8 mm x Thk. 3.0 mm, AR Coating?

A3: Zinc Sulfide windows with AR coatings typically meet ISO 10110 standards for optical components, addressing surface quality, wavefront distortion, and coating durability. They often adhere to MIL-C-675 standards for coating adhesion and durability requirements. Manufacturers may also hold ISO 9001 certification to ensure consistent quality management. Compliance with RoHS and REACH regulations can be relevant, depending on the application and regional requirements.

1. Applications in Advanced Industries

Zinc sulfide windows with a diameter of 50.8 mm and thickness of 3.0 mm, combined with an anti-reflective (AR) coating, are widely employed in sectors that require precise infrared imaging and sensing. Their performance is particularly valued in defence and security systems, where durability and excellent transmissivity in the mid-wave to long-wave infrared range are essential for reliable target detection. Additionally, their solid mechanical properties and resistance to abrasion make them suitable for demanding environments, such as aerospace applications.

Engineers across various sectors also rely on these ZnS windows for research and medical instrumentation, where precise measurement and minimal optical distortion are of paramount importance. The AR coating significantly reduces reflection loss, enabling maximum throughput and superior image clarity. As industries continue to incorporate advanced optical solutions, the enhanced durability and optical performance of ZnS windows expand their role in remote sensing, infrared payloads, and emerging photonics research.

2. Comparative Analysis with Alternative Materials

Compared to other infrared-transparent materials like germanium or sapphire, ZnS windows deliver an exceptional balance between optical clarity and structural strength. Their notable transparency across a broader wavelength range makes them a compelling choice for applications that span both the mid-wave and long-wave infrared spectra. The relatively low density of zinc sulfide further contributes to overall system weight reduction, which is advantageous in size- and weight-sensitive equipment.

In addition, ZnS windows often exhibit better thermal shock resistance than more brittle alternatives. When configured at a diameter of 50.8 mm and thickness of 3.0 mm, these windows withstand mechanical stresses while maintaining stable optical performance. The AR coating further differentiates them by minimising light reflection, enhancing transmission, and ensuring consistent performance under diverse conditions. This combination of optical efficiency, durability, and versatility underscores why ZnS windows remain a preferred choice for high-precision infrared systems.
