    摘要: A method for molding a chalcogenide glass lens includes providing a mold. A preformed lens of chalcogenide glass is placed within the mold. The lens has a top surface and a bottom surface. An amount of chalcogenide glass is deposited within the mold and on the top surface of the preformed lens. The mold is heated, such that the chalcogenide glass on the top surface of the preformed lens softens, melts, and bonds to the top surface of the preformed lens. A lens surface is formed in the melted chalcogenide glass to form a molded lens which is bonded to the top surface of the preformed lens. The molded lens and preformed lens assembly is then removed from the mold.

    摘要: An object of the present invention is to provide a press forming machine for glass optical devices which is superior in the temperature uniformity and has a low manufacturing cost. An upper die is fixed to a lower end of a fixed shaft, and a lower die is fixed to an upper end of a moving shaft. The upper die and the lower die are accommodated in a quartz tube, and a forming chamber in which atmosphere adjustment is possible is formed inside the quartz tube. An infrared lamp unit is arranged so as to surround the quartz tube. The infrared lamp unit is constituted by a plurality of straight tube type infrared lamps each of which has a vertical axis, and a reflecting mirror is arranged behind each infrared lamp. In this example, straight tube type infrared lamps are used in the infrared lamp unit.

    摘要: Disclosed is a mold including upper and lower molds for obtaining glass optical elements by press molding a glass molding material softened by heat, in which either one of the upper and lower molds is made of a ceramic matrix and the matrix has no surface hole having a diameter of 300 microns or more on the molding surface, and a method for manufacturing glass optical elements using the mold. For example, on the upper mold 21 and the lower mold 22, formed is a &bgr; type silicon carbide having a thickness that a molding surface can be reproduced by grinding and a density of 3.20 g/cm3 or more so as to include at least the molding surface facing a surface of the glass molding material G. The mold according to the invention can be reused even where pullouts occur from repetitive use.
