摘要:
The optical elements are made from an opto-ceramic material that is characterized by high density, transparency for visible light and IR, high refractive index, high Abbe number and outstanding relative partial dispersion. Mixed oxides are sintered to obtain the opto-ceramic material. The mixed oxides contain zirconium oxide and hafnium oxide mixed with one or more oxides of yttrium, scandium, lanthanide elements, and optionally mixed with one or more of SiO2, Na2O, and TiO2. Alternatively the mixed oxides contain zirconium oxide and hafnium oxide mixed with CaO and/or MgO and optionally mixed with one or more of SiO2, Na2O, and TiO2. In addition, the mixed oxides can also include one or more oxides of Al, Ga, In, and Sc; optionally one or more oxides of yttrium, some lanthanide elements; and optionally one or more of SiO2, Na2O, MgO, CaO, and TiO2.

The refractive, transmissive or diffractive optical elements are made from a ceramic containing one or more oxides of the type X2O3, which is transmissive for visible light and/or for infrared radiation and which has a cubic crystal structure analogous to that of Y2O3. In preferred embodiments X is Y, Sc, In, or a lanthanide element, namely La to Lu, and in particular is Lu, Yb, Gd, or La. Also mixtures of oxides of the type X2O3 with oxides having different stoichiometries, such as HfO2 and/or ZrO2, may be present, as long as the cubic structure of the ceramic is maintained.

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 present invention relates to a process for producing optical elements, in particular lenses made from an optoceramic, comprising a forming step, which step comprises the formation of a green body. The invention further relates to optical elements produced according to the before mentioned process.The process according to the present invention comprises a forming step including the application of a mould being close to the final geometry of the body to be formed (near net shape principle) including the application of moderate pressure between 0.1 MPa and 50 MPa, preferably between about 0.5 MPa and 25 MPa, in particular preferred between about 1 MPa und 12 MPa. The pressure is applied either on the ceramic powder mass during positioning of the ceramic powder mass into the form or is applied onto the ceramic powder mass within the form.
