    摘要: An infrared absorption filter consisting of 70 to 98 mol % of SiO2, 1 to 12 mol % of CuO and 1 to 18 mol % of a network modifier oxide than CuO or CdO is provided. A process of fabricating an infrared absorption filter is also provided. The process comprises introducing a divalent copper compound and a compound of a metal species acting as a network modifier oxide in the form of metal ions into a wet gel. The wet gel can be dipped in a dipping solution to precipitate the divalent copper compound and the compound of a metal species acting as the network modifier oxide in the wet gel. The wet gel can be dried and heated, thereby obtaining an infrared absorption glass. The infrared absorption glass can be cut and polished, thereby fabricating a filter.

    摘要: A surface light shaping diffuser (LSD) is formed from a monolithic glass material by recording light shaping structures on a surface of the material during its formation. A surface LSD is produced by embossing or molding light shaping structures onto a high quality optical glass or by embossing light shaping structures on a glass film layer coated onto a substrate. A rubber submaster carrying the light shaping structures is used as the master in such diffusers control the angular spread of transmitted light while homogenizing otherwise spatially noisy light sources such as LCDs and filamented light sources and while maintaining damage thresholds consistent with any glass optical element. The surface LSD has a transmission efficiency of over 90% from the Ultraviolet wavelengths through the physical spectrum and into the near-infrared.

    摘要: A method of producing a homogeneous metal oxide fiber having high denseness and free of voids that may adversely affect the electro-optic characteristic of the fiber, and a metal oxide fiber produced according to the method. The method comprises:a first step of forming a gel-form fiber from a sol obtained by concentrating a solution composed of a metallic compound, water and a solvent to the extent that the solution exhibits a spinnable behavior;a second step of decomposing and eliminating organic components out of the gel-form fiber obtained at the first step; anda third step of solidifying the gel-form fiber obtained at the second step;the second step and/or the third step being carried out while heating is made in a water vapor atmosphere.

    摘要: The invention is a sol-gel extrusion process which allows fabrication of both thick and thin wall tubes. For example, the process is capable of preparing silica overcladding tubes in a manner easier than sol-gel casting processes, and also capable of preparing relatively thin substrate tubes, which are difficult to cast. According to the invention, a silica dispersion containing a stabilizing agent is provided, a gelling agent is added to the dispersion to induce gellation, and the resultant gel is extruded into a silica body, in the substantial absence of polymeric material from the gel. Substantially avoiding the inclusion of such polymeric material in overcladding and substrate tubes offers significant commercial advantages by reducing the time and energy required to remove organic materials from the tube bodies, by reducing environmental impact, and by reducing the amount of impurities introduced in the tubes.

    摘要: The invention provides a process of obtaining a gradient index type of optical element with profiles of first and second metal component concentrations by the sol-gel method. The process of fabricating a gradient index type of optical element comprises steps of dipping a silicon component-containing wet gel prepared by the sol-gel method in a solution containing an alkoxide of at least one metal component selected from a first group consisting of Ti, Nb, Ta, and Zr or a derivative thereof to thereby impart to the wet gel a concentration gradient with a concentration of the first metal component decreasing from a periphery to a center of the wet gel, allowing at least one metal component selected from a second group consisting of Ba, La, Y, Gd, Sr, Ca, and Zn to be dissolved out of the wet gel to thereby impart to the wet gel a concentration gradient with a concentration of the second metal component increasing from the periphery to the center of the wet gel, and drying, and firing the wet gel.
