Abstract

A lens (101) produced from a radial rays-curing material comprises a lens proper portion (102) that serves as an optically effective part of the lens (101), and a circular flange portion (103) that surrounds the lens proper portion (102) and serves as an optically non-effective part of the lens (101). The circular flange portion (103) has front and rear surfaces (103a, 103b) that are different in appearance.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP2006-233727 filed in the Japan Patent Office on Aug. 30, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an optical element or lens using an ultraviolet-curable resin or the like as a material, and a manufacturing apparatus (production apparatus) for manufacturing the optical element. Background technique [0004] In optical elements (such as lenses, etc.) used in optical instruments such as cameras, etc., there are generally two types: one made of glass and the other made of resin. Compared with optical elements made of glass, optical elements made of resin are light in weight, excellent in impact resistance, and low in cost, and therefore, resin-based optical elements have recently been widely used in the field of optical instruments. [0005] For t...
