Abstract:
1. A coating apparatus, comprising: a centering device for determining a center of a lens; a lens height measuring device for measuring a gradient of the lens ranging from a center on a face side of the lens to an edge portion on the face side of the lens; a primer fluid applicator device for coating a primer coating fluid onto the face side of the lens by an ejection nozzle; a primer spinning device for rotating the lens coated with the primer coating fluid at a rotational speed conformed to the gradient of the lens; a drying device for drying the primer coating fluid coated onto the lens; a photochromic fluid applicator device for coating a photochromic coating fluid onto a primer film coated onto the lens; a photochromic spinning device for rotating the lens coated with the photochromic coating fluid at a rotational speed conformed to the gradient of the lens; and a UV device for irradiating the lens, which has been coated with the photochromic coating fluid, with UV light in a nitrogen atmosphere to cure a coating layer, wherein each of the centering device, the lens height measuring device, the primer spinning device, the drying device, the photochromic spinning device, and the UV device has a lens support portion for supporting the lens, and a lens transport means capable of transferring the lenses is provided.
