摘要： The opto-ceramics and optical elements of the present invention are transmissive to visible light and/or to infrared radiation. They consist of a crystal combination in which individual crystallites have a cubic structure of the type Y2O3 and are made from In2O3 or a mixture of oxides of the type X2O3 in which X=Y, Lu, Sc, Yb, In, Gd, or La. Also mixtures of X2O3 with oxides having different stoichiometries, such as zirconium and hafnium oxide, are possible, as long as the cubic structure of the opto-ceramic is maintained. The optical elements prepared from the opto-ceramics are particularly suitable for mapping optics, such as objectives having reduced chromatic aberrations, in particular with approximately apochromatic mapping behavior. The optical elements of the present invention may be used in lens systems in combination with lenses of glass, but also with other ceramic lenses.

摘要： The present invention addresses a mould for forming a ceramic green body useful for producing at least one optical lens consisting of optoceramics. The invention further refers to the use of such a mould.The (negative) form of the mould is close to the final geometry of the body to be formed (near net shape principle), at least regarding one functional area of at least one surface of the lens to be formed, which can be described by the following equation: y   1 = c  (  x  + b ) 2 1 + 1 - ( k + 1 )  c 2  (  x  + b ) 2 + a 1  (  x  + b ) 2 + a 2  (  x  + b ) 4 + a 3  (  x  + b ) 6 + a 4  (  x  + b ) 8 + …  , ( equation   B ) wherein b is a constant and amounts to >zero and describes the deviation of the negative form of the mould from the form of the surface of the at least one lens.The present invention is based on the idea that already when forming the green body of a later optical element a mould close to the final geometry of the body to be formed (near net shape principle) is used, ending up with a green body being already close to the geometry of the envisaged final optical element.

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.
