Radiation Resistant Optical Glass

SCHOTT's Radiation Resistant Optical Glass is doped with Cerium which provides stability against transmission loss caused by ionizing radiation. The added Cerium gives a yellow tint, while shifting the UV transmittance edge to a longer wavelength. SCHOTT offer several types with different dispersion properties:​
