Schott IRG 25 Infrared Chalcogenide Glass
Categories: Ceramic; Glass; Optical; Sulfide/Chalcogenide

Material Notes: IRG 25 has excellent transmission in the SWIR, MWIR, & LWIR. Physical properties such as low dn/dT and low dispersion enable optical engineers to design color corrected optical systems without thermal defocusing. IRG 25 is optimized for pairing within the family of IR glasses and with other IR materials to support cost effective and high performance optical designs. Furthermore, IRG 25 can be processed by conventional grinding and polishing, single point diamond turning, or molding to support low to high volume component level fabrication.
