Japanese Patent JP3290999

Kind Code:

B2

Abstract:

Antireflection films are coated on the both sides of an optical lens by sputtering in a sputtering system. In a vacuum processing chamber (22) for performing the sputtering, a plurality of optical lens base materials are placed transversely on a substrate holder (26). The holder (26) is set rotatably in a vacuum atmosphere. The optical lens base materials are embedded to holes (26a) formed in the holder (26), facing their concave surface up, by using ring-shaped holding tools (52, 152). The height of the ring-shaped holding tool (52) is larger than the height of the edge of the optical lens base material (11) within the limits of 2 mm when the thickness of the lens edge of the optical lens base material is large. Part of the ring-shaped holding tool (152) which is put together with the upper surface of the optical lens base material (111) is tapered when the thickness of the lens edge of the optical lens base material is small.
