Abstract
The optoceramics are transparent to visible light and/or infrared radiation. The optoceramics each consist of a crystal matrix, i.e. of polycrystalline material, wherein at least 95% by weight, preferably at least 98% by weight, of the single crystallites have a cubic pyrochlore or a fluorite structure. Refractive, transmissive or diffractive optical elements made with the optoceramics, their uses and an optical imaging system comprising at least one of the optical elements are also disclosed. Methods of manufacturing the optoceramics are described.
