    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: A method for producing perforated work pieces from glass, glass ceramics, or semiconductors in a stress-relieving manner is provided. The method includes heating the work piece up to the glass transition temperature and perforating the work piece using a high-voltage electric field of suitable frequency or pulse shape. Then, the perforated work piece is allowed to cool down from the transition temperature range to room temperature at a rate at which the mechanical stresses generated by the perforation process relax.
