| 20080204889 | Method for Manufacturing Optical Element of Refractive Index Distribution Type - The present invention provides a method of producing a graded refractive index optical element, the method being capable of easily forming a graded refractive index distribution in a desired portion of a glass substrate without the need for a specific treatment atmosphere, and without using a molten salt. More specifically, the present invention provides a method of producing a graded refractive index optical element comprising applying a paste containing a copper compound, an organic resin and an organic solvent to a glass substrate containing an alkali metal component as a glass component, and then performing heat treatment at a temperature below the softening temperature of the glass substrate. | 08-28-2008 |
| 20080226248 | Process for Producing Optical Device - The present invention provides a method of producing an optical element without the need for high vacuum, unlike the thin film deposition methods, and without using a molten salt. More specifically, the invention provides a method of producing an optical element comprising applying a paste containing at least one compound selected from lithium compounds, potassium compounds, rubidium compounds, cesium compounds, silver compounds, and thallium compounds, an organic resin, and an organic solvent to a glass substrate containing an alkali metal component as a glass component and then performing heat treatment at a temperature below the softening temperature of the glass substrate. | 09-18-2008 |
| 20090163343 | Blue-Violet Light Blocking Glass - The present invention provides a blue-violet light blocking glass containing copper (I) halide fine particles that satisfactorily transmits light having a wavelength of 450 nm to 600 nm and sharply blocks light having a wavelength shorter than 450 nm. | 06-25-2009 |
| 20090231830 | Transparent White Fluorescent Glass - A transparent white fluorescent glass is provided which contains a soda lime glass as a base material, 0.8 to 2.5 wt % of Sn, calculated as SnO, and 0.045 wt % or less of Fe, calculated as Fe | 09-17-2009 |
| 20100165454 | Method for Manufacturing Gradient-Index Optical Element Having Infrared Absorbing Ability - A method of readily producing a gradient optical element having infrared absorbing ability by easily forming a refractive index distribution in a desired portion of a glass substrate having infrared absorbing ability without requiring a specific treatment atmosphere nor using a molten salt. | 07-01-2010 |
| 20100214788 | Glass Substrate With Light Directivity and Illuminator Employing the Same - The present invention provides a high-precision planar light source with a sufficiently uniform luminance and sufficient light directivity to direct light to travel in a specific direction, using a simple production process. More specifically, the invention provides: a glass substrate with light directivity produced by applying a paste containing at least one member selected from the group consisting of lithium compounds, sodium compounds, potassium compounds, rubidium compounds, cesium compounds, copper compounds, silver compounds, and thallium compounds, an organic resin, and an organic solvent to one or both sides of a glass substrate containing an alkali metal as a glass component, and then performing heat treatment at a temperature lower than the softening temperature of the glass substrate; and a planar light source using the glass substrate. | 08-26-2010 |
