Abstract

Abstract An optical element and a method for manufacturing same containing therein a pattern or patterns having both photochromic and fluorescence-quenching properties, wherein ions having such properties are penetrated in a desired pattern into a fluorescent glass base containing therein ion-exchangeable ions to cause ionexchanging between the penetrated ions and the existing ions in the glass base, thereby forming, at the interior of the glass base, mechanically and chemically stable patterns.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 106 words
An optical element containing therein a pattern having photochromic and fluorescence-quenching properties and another pattern having the fluorescence-quenching property alone, which comprises in combination: a. a fluorescent glass body containing therein an ion-exchangeable ion; b. a first metal ion capable of inducing both photochromism and fluorescence-quenching; and c. a second metal ion other than said first metal ion capable of inducing the fluorescence-quenching alone, said ion-exchangeable ion in said glass body being ion-exchanged with said first and second metal ions to enable said metal ions to be penetrated into said glass body and to form the required patterns in the inner surface of said glass body.
Claim 2
Dependent Claim 106 words
An optical element containing therein a pattern having photochromic and fluorescence-quenching properties and another pattern having the fluorescence-quenching property alone, which comprises in combination: a. a fluorescent glass body containing therein an ion-exchangeable ion; b. a first metal ion capable of inducing both photochromism and fluorescence-quenching; and c. a second metal ion other than said first metal ion capable of inducing the fluorescence-quenching alone, said ion-exchangeable ion in said glass body being ion-exchanged with said first and second metal ions to enable said metal ions to be penetrated into said glass body and to form the required patterns in the inner surface of said glass body.
Claim 3
Dependent Claim 104 words
AN OPTICAL ELEMENT CONTAINING THEREIN A PATTERN HAVING PHOTOCHROMIC AND FLUORESCENCE-QUENCHING PROPERTIES AND ANOTHER PATTERN HAVING THE FLUORESCENCE-QUENCHING PROPERTY ALONE, WHICH COMPRISES IN COMBINATION: A. A FLUORESCENT GLASS BODY CONTAINING THEREIN AN IONEXCHANGEABLE ION; B. A FIRST METAL ION CAPABLE OF INDUCING BOTH PHOTOCHROMISM AND FLUORESCENCE-QUENCHING; AND C. A SECOND METAL ION OTHER THAN SAID METAL CAPABLE OF INDUCING THE FLUORESCENCE-QUENCHING ALONE, SAID ION-EXCHANGEABLE ION IN SAID GLASS BODY BEING IONEXCHANGEED WITH SAID FIRST AND SECOND METAL IONS TO ENABLE SAID METAL IONS TO BE PENETRATED INTO SAID GLASS BODY AND TO FORM THE REQUIRED PATTERNS IN THE INNER SURFACE OF SAID GLASS BODY.
Claim 4
Dependent Claim 104 words
AN OPTICAL ELEMENT CONTAINING THEREIN A PATTERN HAVING PHOTOCHROMIC AND FLUORESCENCE-QUENCHING PROPERTIES AND ANOTHER PATTERN HAVING THE FLUORESCENCE-QUENCHING PROPERTY ALONE, WHICH COMPRISES IN COMBINATION: A. A FLUORESCENT GLASS BODY CONTAINING THEREIN AN IONEXCHANGEABLE ION; B. A FIRST METAL ION CAPABLE OF INDUCING BOTH PHOTOCHROMISM AND FLUORESCENCE-QUENCHING; AND C. A SECOND METAL ION OTHER THAN SAID METAL CAPABLE OF INDUCING THE FLUORESCENCE-QUENCHING ALONE, SAID ION-EXCHANGEABLE ION IN SAID GLASS BODY BEING IONEXCHANGEED WITH SAID FIRST AND SECOND METAL IONS TO ENABLE SAID METAL IONS TO BE PENETRATED INTO SAID GLASS BODY AND TO FORM THE REQUIRED PATTERNS IN THE INNER SURFACE OF SAID GLASS BODY.

A method for manufacturing an optical element containing therein a pattern having photochromic and fluorescence-quenching properties and another pattern having the fluorescence-quenching property alone, which comprises steps of: a. forming film layers of a first metal having the photochromic and fluorescence-quenching properties and a second metal having the fluorescence-quenching property in a desired pattern on one surface part of a fluorescent glass body containing therein an ion-exchangeable ion; b. causing said film layers of the first and second metals to ionize; and c. ion-exchanging said ionized layers of said first and second metals contacted on said glass surface with said ion-exchangeable ion contained in said glass body to enable said first and second metal ions to penetrate into said glass body.
Claim 10
Independent Claim 121 words
A method for manufacturing an optical element containing therein a pattern having photochromic and fluorescence-quenching properties and another pattern having the fluorescence-quenching property alone, which comprises steps of: a. forming film layers of a first metal having the photochromic and fluorescence-quenching properties and a second metal having the fluorescence-quenching property in a desired pattern on one surface part of a fluorescent glass body containing therein an ion-exchangeable ion; b. causing said film layers of the first and second metals to ionize; and c. ion-exchanging said ionized layers of said first and second metals contacted on said glass surface with said ion-exchangeable ion contained in said glass body to enable said first and second metal ions to penetrate into said glass body.
Claim 11
