SCHOTT Chalcogenide Window Substrates

×
  • 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.
