Publication number: 20040247826Abstract: A method for joining glass ceramic surfaces to each other and/or other types of surfaces using a silicate liquid is disclosed. The products are suitable for use as, e.g. mirror blanks or microlithography stages, at low temperatures. Component pieces are polished then joined at low temperature using a silicate-containing joining liquid. Assembly is then performed in such a way that the joining liquid forms an interface between each component. After a period of low or slightly elevated temperature curing, rigid joints are formed throughout and the composite is dimensionally, vibrationally, and temperature stable and can withstand tensile stresses >4000 psi. The room-temperature cured composite can be heat treated using a slow, systematic temperature increase to dehydrate the joints. A sealing coating may optionally be provided to prevent excess dried joining liquid from flaking off the formed joint.Type: ApplicationFiled: June 23, 2003Publication date: December 9, 2004Inventors: Samuel David Conzone, Alexander J Marker, Joseph S Hayden, Robert D Simpson

Publication number: 20040212302Abstract: A white cold light source uses an LED or a gas discharge lamp and a luminescent rare earth doped glass comprising multiple rare earth cations and a particularly high total rare earth content to generate white light emission. Preferably, the luminescent glass has a 2700K to 7000K black body temperature and color rendering index value exceeding 80. A first embodiment of the glass is composed primarily of P2O5, Al2O3, and alkaline earth and alkali earth oxides, and possesses other properties such as physical and thermal properties that are compatible with conventional melting, forming and other manufacturing steps. Other embodiments of the luminescent glass have a maximum water content of 0.1 wt-% and do not contain any boron. Also the luminescent glass is preferably free of water, boron oxides and nitrides. The luminescent glass can be used as a wavelength converter to produce bright white light emission when pumped by conventional commercially available blue and UV light emitting diode sources.Type: ApplicationFiled: March 11, 2004Publication date: October 28, 2004Inventors: Martin Letz, Ulrich Peuchert, Markus Schweizer, Bernd Drapp, Wolfram Beier, Karina Seneschal, Axel Engel, Joseph S.

Publication number: 20040106018Abstract: 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.Type: ApplicationFiled: July 8, 2003Publication date: June 3, 2004Applicant: SCHOTT GLASS TECHNOLOGIES, INC.Inventors: Samuel David Conzone, Joseph S.
