    摘要: The invention relates to an optical hybrid lens. According to the invention, the lens consists of a substrate (1) that consists of a ceramic having a predetermined shape and at least another material (2), which covers a surface of the substrate (1) at least in certain sections in order to form a lens surface. Use of an optical ceramic as a material enables an additional degree of freedom for adjusting the imaging properties of the hybrid lens. The optical ceramic may have a high refractive index and a low dispersion. The other material can be a material that can be deformed or recast at temperatures that are low in comparison to those of the optical ceramic. In particular the other material can be a low-TG glass or a polymer. The other material is directly applied onto the substrate without a further surface finishing being necessarily required. Other aspects of the invention relate to an optical lens group, an optical image acquisition device, and a process for manufacturing a hybrid lens.

    摘要: The invention relates to a glass ceramic armour material consisting (in % by weight in relation to oxide base) of 5-33 SiO2, 20-50 Al2O3, 5-40 MgO, 0-15 B2O3, 0.1-30 Y2O3, Ln2O3, As2O3, Nb2O3 and/or Sc2O3 and 0-10 P2O5. The inventive armour material can also be reinforced with inorganic reinforcing fibres in a quantity of 5-65% by weight, preferably consisting of C, SiC, Si3N4, Al2O3, ZrO2 or Sialon. Said armour material is characterised in that it exhibits a high elasticity modulus and is producible from green glass without to fear a premature crystallisation.
