摘要:
A method for the low temperature joining of similar and/or different phosphate glass by mating at low temperature glass components by an aqueous solution containing phosphorus. In preferred embodiments, the phosphate glasses are polished, cleaned, and brought together with the phosphate-containing solution between the polished surfaces. Vacuum may be applied to assist in making the joint. The composite is optionally heat treated to increase strength, chemical durability, and optical performance. The bond thereby formed has low birefringence, is strong, and is virtually photonically invisible. The joints now make possible, for example, substrates for virtually no loss signal splitters and other high-end optical components at low cost. Large hybrid performs substrates composed of multiple glass components may be prepared and segmented, providing an inexpensive novel substrate for the photonics industry. Active lasing phosphate glasses may be joined by the present invention method to passive non-lasing glasses for use in laser and related applications.

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.
