Radiation-Resistant Glass ZK509
Radiation-resistant glass, also called stabilized glass, is a special optical glass that exhibits very little loss of transmittance and no severe discoloration under high-dose irradiation by energetic photons and particles. It is generally produced by adding CeO₂ to an optical glass formulation before melting. It therefore generally has the same optical constants as the corresponding ordinary optical glass. Its grade designation is formed by adding 500 to the numerical designation of the corresponding ordinary glass; for example, the radiation-resistant grade corresponding to K9 is K509.
