COATING APPARATUS FOR OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2005/084824
Kind Code:
A1
Abstract:
A coating apparatus for an optical lens, wherein a coating device (42) for a coating solution and a light beam radiating device (151) for hardening the coating solution are disposed in a clean room (7). Obstacle lenses (2) are formed of a set of two sheets of lenses, and stored in a coating container (50). The coating device (42) applies the coating solution on the coated surfaces of the obstacle lenses (2) in the coating container (50). When the obstacle lenses (2) formed of a set of two sheets of lenses coated with the coating solution are taken out from the coating container (50), they are stored in a lens rack (120), and closed by the transparent plate of the light beam radiating device (151). Then, with the air in the lens rack replaced with nitrogen gas, hardening treatment for the coating solution is performed by the light beam radiating device (151).
