Zinc Sulfide Sphalerite Substrates
Zinc Sulfide (ZnS) substrates are used in infrared optics, UV detection, electroluminescent devices, thin-film coatings, CO₂ laser windows, and photonic research. ZnS can occur in the cubic sphalerite phase or the hexagonal wurtzite phase. Sphalerite ZnS is especially useful for optical and electronic applications because of its cubic crystal structure and strong optical transparency.
A postdoc requested sphalerite ZnS wafers and asked for available sizes, orientations, polishing options, and pricing.

What Are Sphalerite Wafers?
A sphalerite wafer is a wafer made from a cubic crystal structure material, commonly Zinc Sulfide (ZnS) or Zinc Selenide (ZnSe). This cubic structure is different from the hexagonal wurtzite phase and is useful for optical, infrared, photonic, and detector applications.
- Material: ZnS or ZnSe cubic crystal structure
- Applications: IR windows, UV detectors, optics, phosphors, and photonics
- Surface finish: SSP, DSP, 60/40 polish, or inspection polish
- Research use: nonlinear optics, transmission experiments, and thin-film coatings
What Are Zinc Sulfide (ZnS) Substrates Used For?
ZnS substrates are selected when researchers need a material with strong optical transmission, useful semiconductor properties, and compatibility with optical coating and laser applications.
- Infrared windows: ZnS is used for IR lenses, windows, and optical blanks.
- CO₂ laser optics: ZnS and ZnSe are used as laser window materials.
- UV detectors: ZnS can be used in ultraviolet-sensitive detector research.
- Electroluminescent devices: ZnS is a common host material for light-emitting phosphors.
- Thin-film coatings: ZnS substrates support anti-reflective, dielectric, and protective coatings.
- Photonic applications: ZnS is used in waveguides, optical devices, and transmission studies.
ZnS Substrates Transmissive in the Visible
Researchers often request multispectral or clear ZnS substrates when visible and infrared transmission are required. Important specifications include growth method, scratch-dig quality, surface polish, thickness, and whether the material is standard ZnS or multispectral ZnS.
