Abstract
The refractive, transmissive or diffractive optical elements are made from a ceramic containing one or more oxides of the type XO, which is transmissive for visible light and/or for infrared radiation and which has a cubic crystal structure analogous to that of YO. In preferred embodiments X is Y, Sc, In, or a lanthanide element, namely La to Lu, and in particular is Lu, Yb, Gd, or La. Also mixtures of oxides of the type XOwith oxides having different stoichiometries, such as HfOand/or ZrO, may be present, as long as the cubic structure of the ceramic is maintained.
