Selecting an optical glass for an optical window there is a vast selection of optical glasses made by many manufacturers from around the world, including Schott, Pilkington, and O’hara optical glass. Processing from glass slabs and mouldings to an optical glass window.

For the user of an optical glass the refractive index and the relationship between index and wavelength (dispersion) are particularly important. The refractive index of optical glasses listed in the following pages ranges from 1.51nd to 1.84nd. Optical glass windows are manufactured in a range of optical crown, flint, radiation resistance, non-browning and ndoped optical glasses and can be selected from the following manufacturers glass types.
