| IRG 22 has excellent transmission in the SWIR, MWIR, & LWIR and has the best transmission of the IRG series in the NIR band with transmission beginning as low as 0.7 µm. With physical properties such as low dn/dT and low dispersion enables the optical engineers to design color corrected optical systems without thermal defocusing. IRG 22 is optimized for pairing within the family of IR glasses as well as other IR materials to support cost effective and high performing optical designs. Furthermore, IRG 22 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. |
