摘要： 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. More specifically, the present invention provides a method for producing a gradient-index optical element having infrared absorbing ability, the method comprising applying a paste containing an organic resin, an organic solvent, and at least one compound selected from the group consisting of lithium compounds, potassium compounds, rubidium compounds, cesium compounds, silver compounds, copper compounds, and thallium compounds onto a glass substrate containing an alkali metal component, at least one member selected from the group consisting of iron, copper, cobalt and vanadium, and over 3 wt.% of iron, when contained singly among iron, copper, cobalt and vanadium, on an Fe 2 O 3 basis, taking the total weight of the glass as 100 wt.%, and heating the glass substrate at a temperature below the softening temperature of the glass substrate.

摘要： 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.
