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.
