Zinc Sulfide Window (ZnS) Description
Zinc Sulfide (ZnS) is a premier infrared optical window and substrate material, celebrated for its exceptional performance and reliability. With a broad transmission range from 3 to 13 micrometers (μm), ZnS is the most commonly used material for mid- and far-infrared applications due to its remarkable resistance to deflection and robust physical properties.
Key Features
- Wide Transmission Range: Effective transmission across 3-13μm, optimizing performance in both mid-infrared (8-12μm) and far-infrared bands.
- Consistent Optical Properties: Exhibits excellent refractive index uniformity and consistency, ensuring high-quality image transmission, particularly within the 8-12μm wavelength range. While some absorption begins after 10μm, ZnS maintains superior transmittance in the mid-infrared spectrum.
- Durability and Strength: Possesses strong resistance to harsh environmental conditions and high hardness. ZnS offers twice the breaking strength of zinc selenide (ZnSe), making it highly durable for demanding applications.
- Optimized Performance: Higher transmittance in the mid-infrared band with minimal absorption and scattering at longer wavelengths. As the wavelength decreases, ZnS maintains low levels of absorption and scattering, ensuring clarity and precision in optical applications.
Zinc Sulfide Window (ZnS) Applications
Zinc Sulfide windows are integral components in a variety of infrared optical devices, including:
- Spectroscopic Prisms: Enhance the performance and accuracy of spectroscopic instruments by providing clear and consistent infrared transmission.
- Fourier Transform Infrared (FTIR) Spectrometers: Essential for accurate infrared analysis, ZnS windows contribute to the precision of FTIR spectrometers.
- Infrared Spectrophotometers: Facilitate precise measurement of infrared spectra, ensuring reliable results in spectrophotometric devices.
- Infrared Devices: Widely used in transmission windows and lenses for various infrared systems, delivering dependable and high-quality infrared performance.
