摘要： The present invention relates to low-dispersion optical glass having a low glass-transition temperature suited to precision press molding, a press molding preform comprised of this glass, a method of manufacturing the same, an optical element, and a method of manufacturing the same. The optical glass comprises, given as molar percentages,28 to 50 percent of P 2 O 5 ; more than 20 percent but not more than 50 percent of BaO; 1 to 20 percent MgO; a sum of Li 2 O, Na 2 O, and K 2 O exceeding 3 percent (with 0 to 25 percent of Li 2 O, greater than or equal to 0 percent and less than 10 percent of Na 2 O, and 0 to 12 percent of K 2 O); more than 0 percent but not more than 15 percent of ZnO; 0 to 25 percent of B 2 O 3 ; 0 to 5 percent of Al 2 O 3 ; 0 to 8 percent of Gd 2 O 3 ; 0 to 20 percent of CaO; 0 to 15 percent of SrO; and 0 to 1 percent of Sb 2 O 3 ; with a sum of oxide contents of P, Ba, Mg, Li, Na, K, Zn, B, Al, Gd, Ca, Sr, and Sb being greater than or equal to 98 percent. The press molding preform is comprised of the optical glass. In the method of manufacturing a press molding preform, a glass melt gob of prescribed weight is separated from a glass melt flow, and the press molding preform comprised of the optical glass is formed with the prescribed weight. In the method of manufacturing an optical element, the press molding preform or the press molding preform manufactured by the above method is heated and precision press molded.

摘要： Bei einem bekannten Verfahren zur Herstellung eines Bauteils, das mindestens bereichsweise aus seltenerdmetalldotiertem Quarzglas besteht, wird ein Hohlräume enthaltendes Zwischenprodukts (5) aus einem mit Seltenerdmetall dotierten SiO 2 -Rohstoff in eine Sinterform eingebracht, deren Innenraum von einer kohlenstoffhaltigen Formwandung (9) begrenzt ist und darin durch Gasdrucksintern bei einer Maximal-Temperatur oberhalb von 1500 °C zu dem Bauteil erschmolzen, wobei zwischen der Formwandung (9) und dem Zwischenprodukt (5) eine Abschirmung (6 , 7, 8) angeordnet ist. Um hiervon ausgehend ein modifiziertes Gasdrucksinterverfahren anzugeben, das die Herstellung von Seltenerdmetall-dotiertem Quarzglas mit reproduzierbaren Eigenschaften gewährleistet, wird erfindungsgemäß vorgeschlagen, dass als Abschirmung eine Schüttung aus amorphen SiO 2 -Teilchen mit einer Schichtdicke von mindestens 2 mm eingesetzt wird, deren Erweichungstemperatur um mindestens 20 °C höher ist als die Erweichungstemperatur des dotierten SiO 2 -Rohstoffs, und die zu Beginn des Schmelzens des Zwischenprodukts gemäß Verfahrensschritt gasdurchlässig ist, und die beim Schmelzen zu einer für ein Druckgas gasdichten Außenschicht sintert.
