Abstract
Official abstract text for this publication.
A method for producing a spectacle lens with a base material and a metal atom-containing layer disposed on the base material, the method including: forming the metal atom-containing layer on the base material by electron beam vapor deposition of irradiating, with an electron beam, a vapor deposition source with a carrier that contains at least one granule selected from the group consisting of silicon dioxide (SiO2), zirconium oxide (IV) (ZrO2), and titanium oxide (IV) (TiO2) and carries a metal particle containing at least one metal.
First claim
Opening claim text (preview).
1 . A method for producing a spectacle lens with a base material and a metal atom-containing layer disposed on the base material, the method comprising: forming the metal atom-containing layer on the base material by electron beam vapor deposition of irradiating, with an electron beam, a vapor deposition source provided with a carrier that contains at least one granule selected from the group consisting of silicon dioxide (SiO 2 ), zirconium oxide (IV) (ZrO 2 ), and titanium oxide (IV) (TiO 2 ) and carries a metal particle containing at least one metal. 2 . The method for producing a spectacle lens according to claim 1 , wherein the average particle diameter D50 of the granule is 0.1 to 5.0 mm. 3 . The method for producing a spectacle lens according to claim 1 , wherein the granule is composed only of silicon dioxide (SiO 2 ). 4 . The method for producing a spectacle lens according to claim 1 , wherein the metal particle includes silver. 5 . The method for producing a spectacle lens according to claim 1 , wherein the metal particle contains at least one selected from the group consisting of platinum, gold, palladium, mercury, cadmium, cobalt, nickel, copper, zinc, titanium, molybdenum, and tungsten. 6 . The method for producing a spectacle lens according to claim 1 , further comprising: impregnating the carrier with a liquid containing the metal particle and drying the carrier so that the carrier carries the metal particle. 7 . The method for producing a spectacle lens according to claim 1 , wherein the spectacle lens further has an anti-reflection film disposed on the base material, and the metal atom-containing layer is disposed on the anti-reflection film. 8 . The method for producing a spectacle lens according to claim 1 , wherein the spectacle lens further has an anti-reflection film disposed on the base material, the anti-reflection film is a laminated body with a lamination of a plurality of single layers, and the metal atom-containing layer is disposed between at least one pair of the single layers adjacent to each other. 9 . The method for producing a spectacle lens according to claim 1 , wherein the film thickness of the metal atom-containing layer is at most 5 nm.
