Abstract:
1. A lens coating method comprising: holding a lens by suction to face downward on a suction-holding member configured to rotate on its own axis and to travel with the lens held thereon; then placing the lens facing downward into a coating receptacle by causing the suction-holding member to travel with the lens held thereon, and applying a coating liquid onto the lens from below, thereby forming a coating film; then placing the lens facing downward into a drying receptacle by causing the suction-holding member to travel with the lens held thereon, and drying the coating film by performing drying of the lens; and then placing the lens facing downward into a curing receptacle by causing the suction-holding member to travel with the lens held thereon, and performing a curing process on the coating film by supplying radiation rays or heat to the lens, wherein: the applying the coating liquid is performed while the suction-holding member is caused to hold the lens with a coating suction force and to rotate the lens about the axis, the curing process is performed while the suction-holding member is caused to hold the lens with a curing suction force without rotating the lens about the axis, and the coating suction force is higher than the curing suction force.
