IR Windows
Our IR Window Capabilities
At Koch Crystal, we specialize in the precision fabrication and restoration of infrared windows across a comprehensive range of materials, including NaCl, KCl, KBr, ZnSe, KRS-5, BaF2, AgCl, and CaF2. Our expertise lies in handling the specific optical and mechanical challenges of each substrate—from the broad spectral range of Potassium Bromide to the high-power durability of Zinc Selenide. Utilizing specialized anhydrous polishing techniques, we ensure that even the most sensitive hygroscopic crystals achieve maximum transmission and surface clarity, protecting your optics from fogging and degradation. Whether you require standard spectrophotometer windows or custom-engineered laser-grade solutions, our team delivers the precision necessary for your most demanding analytical and industrial applications.
