The optical glass has a Pt content of at most 1.5 ppm, and is characterized in ... 01/11/07 - 20070010390 - Bismuth containing fluorophosphate glass and method for making thereof New and improved compositions of doped and co-doped bismuth fluorophosphate glasses for lasers is disclosed that have a high refractive index (nD) of approximately 1.6 and higher, high transmission in the near infrared part of the spectrum, and a wide glass forming domain. The disclosed glass systems Al(PO3)3-Ba(PO3)2-Bi(PO3)3-BaF2+RFx+dopands use dopants ... 10/05/06 - 20060223689 - Optical glass, press-molding preform, process for the production thereof, optical element and process for the production thereof the optical glass having a refractive index (Nd) of 1.40 to 1.58 and an Abbe's number (νd) of 67 to 90. ... // - 1 to 30% of Li+, - ... // - 5 to 30% of Al3+, - ... // - 10 to 45% of P5+, - ... 07/27/06 - 20060166806 - Antimicrobial sulfophosphate glass The invention relates to an antimicrobial and anti-inflammatory sulfophosphate glass having the following composition in percent by weight on an oxide basis: P2O5 15-60 percent by weight; SO3 5-40 percent by weight; B203 0-20 percent by Al2O3 0-10 percent by weight; SiO2 0-10 percent by weight; Li2O 0-25 percent by ... 06/15/06 - 20060128549 - Lead-free phosphate glasses Disclosed are zinc niobium phosphate glasses consisting essentially, expressed in terms of mole percent on the oxide basis of, 40-65% P2O5, 25-37% ZnO, 0.1-15% Nb2O5, 0-6% Al2O3, 0-5% Bi2O3, 0-3% Na2O and 0-5% B2O3, said glass exhibiting glass transition temperature below 450° C., a dilatometer softening point below 500° C., ... 05/25/06 - 20060111231 - Use of lead-free and phosphate-containing glasses in a precision moulding process The present invention relates to the use of lead-free and phosphate-containing glasses, preferably coloured and filter glasses which absorb light in the infrared region (IR-region), in a precision moulding process. Preferably, the content of fluorine in the glass is low. Advantageously, so optical constituents can be produced without finishing, such ... 03/09/06 - 20060052230 - Lead-free low softening point glass Disclosed is a lead-free low softening point glass whose composition lies within the system SnO—P2O5 and containing over 5 to 30 mol % of MnO. The addition of MnO allows the water resistance and coefficient of thermal expansion of the glass to be improved without spoiling its feature of a ... 11/17/05 - 20050255985 - Lead-free low softening point glass Disclosed is a lead-free low softening point glass whose composition lies within the system, SnO—P2O5 and containing over 5 to 30 mol % of MnO. The addition of MnO allows the water resistance and coefficient of thermal expansion of the glass to be improved without spoiling its feature of a ... 10/20/05 - 20050233888 - Antimicrobial phosphate glass with adapted refractive index wherein the sum formed from TiO2 and ZrO2 and BaO and La2O3 and Cr2O3 and Nb2O3 lies in the range of 0.01-40 wt % and the sum formed from Ag2O and ZnO and CuO and Cr2O3 and I and TeO2 and GeO2 lies in the range of 0.1-40 wt % ... 09/01/05 - 20050192174 - Optical glass for precision molding 0 to 12% ... // - 12 to 67% - ... // - 1 to 10% - ... // - 24 to 43% - ... // - 3 to 20% - ... 07/28/05 - 20050164862 - Optical glass, shaped glass material for press-molding, optical element and process for producing optical element Disclosed is an optical glass having high-refractivity and high-dispersion properties and having little coloring, said glass containing P2O5, Nb2O5 and TiO2 as glass components, containing Sb2O3 in an amount of over 0% by weight but not more than 1% by weight based on the total content of the glass components ... 07/21/05 - 20050159290 - Optical glass for precision molding 0 to 7% ... // - 34 to 60% - ... // - 20 to 35% - ... // - 15 to 29% - ... ### FreshPatents.com Support |
