摘要： PURPOSE:To obtain optical glass having a high transmittance within an ultraviolet region with hardly any deterioration in the transmittance due to irradiation with ultraviolet rays by melting glass with a limited component composition and containing specific amounts of especially SiO2, B2O3 and BaO added thereto and forming the resultant melt. CONSTITUTION:Ultraviolet ray transmitting glass prepared by melting glass having the following composition. The aforementioend composition is 15-50wt.% SiO2, 10-40wt.% B2O3, 10-50wt.% BaO, 0-20wt.% CaO, 0-20wt.% SrO, 0-15wt.% ZnO, 0-15wt.% La2O3, 0-10wt.% MgO, 0-15wt.% Al2O3, 0-5wt.% K2O,

摘要： PURPOSE:To mold glass lens with slight influence of strain of shrinkage and deformation free from fusing between mold and glass, by coating the surface of glass lens having a high softening point with a viscous solution containing glass fine particles having a low softening point, drying and press molding the glass at the softening temperature of the glass having a low softening point. CONSTITUTION:The surface of previously abraded glass lens 1 having a high softening point is coated with a viscous solution containing fine particles having a low softening point to prepare blanks, the viscous solution is dried and blanks are calcined at a temperature lower than the softening temperature of the glass having a high softening point and higher than the softening temperature of the glass having a low softening point. The calcined blank is placed on a mold 3 in such a way that the glass lens 1 having a high softening point is down and stuck glass 13 is upside. The mold 3 is heated through a heating plate 4a by a heater 6. A mold 5 is moved down in a state where the stuck glass 13 is >= at the softening point and the blank is press molded. Glass lens of nonspherical surface, etc., can be readily obtained by press molding, etc., stress is not applied on the bonded face of the blank since a lens part 12 of nonspherical surface is thin and no strain is produced in the bonded face.

摘要： PURPOSE:To easily obtain the lens which is free from sink marks by constituting a lower mold of a specific material to impart prescribed surface roughness to the mold in the apparatus equipped with the upper mold having a glass melting crucible, a molten glass dropping nozzle, the lower mold for receiving a glass drop and an upper mold for compression-molding the glass drop cooperatively with the lower mold. CONSTITUTION:The lower mold 12 for receiving the glass drop is constituted of the material having >=50W/mK thermal conductivity (e.g.: Ag, graphite, SiC, AlN, Si, cemented carbide) and is thereby provided with 0.05 to 0.2muRmax surface roughness in the device equipped with the glass melting crucible 1, the nozzle 4 which is provided in the bottom of the crucible 1 and drops the molten glass 2 as the glass drop 6, the lower mold 12 for receiving the glass drops which receives the glass drops 7, 10 dropped from the nozzle, and the upper mold 13 for compression molding of the dropped glass drop 10 cooperatively with the lower mold 12.

摘要： PURPOSE:To allow the production of a glass drop of a large weight by providing means for blasting air to the glass drop formed at the tip of a nozzle from the direction below the glass drop. CONSTITUTION:The glass 2 is melted in a crucible 1 and is kept heated by heaters 5a to 5d so that the molten glass does not cool to a solid state and the glass drop 6 is formed at the tip of the nozzle 4. The hot air is blasted to this glass drop 6 from the direction below the glass drop 6 by a blowing up part 9 of a doughnut shape or the like which sends the hot air from a blasting hole 16 through, for example, a blasting pipe 17, by which the glass drop 6 is increased in size; thereafter, the glass drop is allowed to fall by gravity. The glass drop is captured in a mold 12 and is thereafter moved from the falling point. The glass drop is then pressed by an upper mold 13.
