IRG 23 has excellent transmission in the SWIR, MWIR, & LWIR and has the highest refractive index of the IR series glasses. Physical properties such as low dn/dT and low dispersion enable optical engineers to design color corrected optical systems without thermal defocusing. IRG 23 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 23 can be processed by conventional grinding and polishing, single point diamond turning, or molding to support low to high volume component level fabrication.Information provided by SCHOTT. |
