SCHOTT IRG Infrared Glasses
Lightweight with Broad Transmission Bands in the SWIR, MWIR, and LWIR Spectra
Ideal Alternative to Germanium

SCHOTT Chalcogenide Glass Windows are suitable for a large range of IR applications and are an ideal alternative to Germanium substrates. Available in 5 different glass types optimized for excellent transmission in the NIR-LWIR ranges, these windows feature low dn/dt and dispersion with high color correction. Low density, coefficient of thermal expansion, and chemical resistance make them a great choice for low SWaP applications and harsh environments with changing temperatures. SCHOTT Chalcogenide Glass Windows are available in a standard 25.4mm diameter and a 3mm thickness. These windows are ideal for ideal for thermal imaging, spectroscopy, and sensing applications.

Note: Gloves must be worn while handling all IRG materials. IRG27 is a toxic material that can be absorbed through the skin. For all IRG materials, care should be taken when handling as these materials are soft and susceptible to scratches. These materials should be stored in a low humidity environment and extended exposure to UV light should be avoided to avoid the development of haziness on the surface of the optic. Contact with high temperatures or strong acids or bases should be avoided.

IRG22 – Offers excellent transmission in the NIR range. Chemical Formula Ge₃₃As₁₂Se₅₅
IRG24 – Offers a low coefficient of thermal expansion for heat-sensitive applications. Chemical Formula Ge₁₀As₄₀Se₅₀
IRG25 – Offers excellent SWIR, MWIR, and LWIR transmission. Chemical Formula Ge₂₈Sb₁₂Se₆₀
IRG26 – Offers an exceptionally broad transmission range, with minimal absorption at 12.5um. Germanium Free. Chemical Formula As₄₀Se₆₀
IRG27 – Combines a high SWIR/MWIR transmission with a low coefficient of thermal expansion. Germanium Free. Chemical Formula As₂S₃
