Infrared Crystal — Lithium Fluoride (LiF) Optical Windows & Components
High-transmission lithium fluoride crystal discs and windows (LiF) for infrared optics, spectrometers, and thermal imaging — outstanding transmission across a wide UV–IR range, very low absorption and dispersion, excellent optical clarity and low refractive index for minimal reflection losses.
High-purity Barium Fluoride (BaF₂) infrared crystals for precision windows, lenses and prisms — offering broad UV→mid-IR transmission (≈0.15–12 µm), low dispersion for reduced chromatic aberration, strong throughput at CO₂ laser bands, and high optical homogeneity for spectroscopy, thermal imaging and laser applications.
Infrared Crystals — Calcium Fluoride (CaF₂) Windows & Lenses
High-purity Calcium Fluoride (CaF₂) infrared crystals for precision windows, lenses and prisms — offering broad deep-UV to mid-IR transmission (~0.13–8 µm), low dispersion for reduced chromatic aberration, low fluorescence and excellent optical homogeneity for spectroscopy, imaging and laser applications.
Infrared Crystals — Zinc Selenide (ZnSe) Optical Windows & Discs
High-transmission zinc selenide discs and windows for infrared optics and CO₂ laser systems — outstanding mid- to long-wave IR throughput, very low absorption at 10.6 µm, good thermal shock resistance and suitability for high-power laser beam delivery and thermal imaging.
High-performance Zinc Sulfide (ZnS) infrared crystals for IR windows, domes and precision lenses — delivering broad mid- and long-wave IR transmission (typ. ~0.45–12 μm), low bulk absorption at CO₂-laser bands, high refractive index for compact optical designs, good environmental durability, and excellent machinability for diamond-turning or precision polishing.
Germanium (Ge) Optical Windows & Discs
High-refractive-index germanium windows and discs for mid- to long-wave infrared systems — outstanding transmission across key MWIR/LWIR bands (commonly ~2–14 µm), very low bulk absorption at thermal-imaging wavelengths, and high refractive index for compact, high-performance lenses and detector windows.
