The invention relates to aluminophosphate-based glasses suitable for use as a solid laser medium, which further contains SiOand BO. The laser glasses possess desirable figure of merit values for FOMand FOM, as described herein.

Aluminophosphate glass composition

The invention relates to an optical hybrid lens. According to the invention, the lens consists of a substrate () that consists of a ceramic having a predetermined shape and at least another material (), which covers a surface of the substrate () 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.
