The optoceramic has the following formula: A | 08-05-2010 |
20100193739 | ACTIVE OPTOCERAMICS WITH CUBIC CRYSTAL STRUCTURE, METHOD OF PRODUCTION OF THE OPTOCERAMICS, AND USES THEREOF - The transparent polycrystalline optoceramic has single grains with a symmetric cubic crystal structure and at least one optically active center. The optoceramic has the following formula: A | 08-05-2010 |
20100248932 | METHOD OF PRODUCING TRANSPARENT CERAMICS - The method of making a transparent ceramic includes making a molded body from a powder mixture of starting materials, which include one or more sintering aids. The sintering aids can include SiO | 09-30-2010 |
20100248938 | PASSIVE OPTOCERAMICS WITH CUBIC CRYSTAL STRUCTURE, PROCESS FOR MANUFACTURING THE SAME AND THEIR USES - 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. | 09-30-2010 |
