Schott IRC-1 Zinc Sulfide Broadband Infrared Ceramic
Categories: Ceramic; Sulfide/Chalcogenide

Material Notes: Zinc Sulfide is suitable material for broadband infrared windows, domes and optics. No other material offers this combination of optical properties and environmental resistance. SCHOTT has developed a ceramic process to produce polycrystalline Zinc Sulfide, IRC-1. IRC-1 has significantly improved optical and mechanical performance compared to CVD processed material.
IRC-1 is the material of choice for mid and long wave IR applications


  • IRC-1 performs with high transmission between 3 – 12 µm
  • Fine grained and homogenous microstructures
    • Higher Strength and Hardness
    • Lower cost finishing
    • Improved results from deterministic finishing
  • Ceramic process allows the production of near net shape dome blanks and curved window blanks
    • Reduces processing time and associated costs
    • Reduces production complexity
