SCHOTT has introduced IRG 27, a classic chalcogenide glass (As2S3), possessing transparency from approximately 0.65 μm to well into the long-wavelength IR (> 10 μm). Additionally, this glass exhibits an extremely small thermo-optic (dn/dT) value for most of its transparency range, a critical attribute in certain applications. Relatively low density and a good thermal expansion match to aluminum are further useful characteristics of IRG 27.
