A light irradiation device () includes a UV lamp (), first and second optical filters () which transmit and block wavelengths within different specific ranges, and a filter switching mechanism () which selectively interposes the first and second optical filters () between the UV lamp () and an optical lens. The blocking wavelength of the first optical filter () is relatively longer than that of the second optical filter (). The first optical filter () is interposed between the UV lamp () and the optical lens since the start of curing a coating solution until a lapse of a predetermined period of time. When the predetermined period of time has elapsed, the second optical filter () is interposed between the UV lamp () and the optical lens to replace the first optical filter ().

Optical lens coating apparatus

The present invention provides an optical member having a plastic substrate and a multilayered antireflection film formed by vapor deposition, wherein at least one layer in the antireflection film is a hybrid layer formed of at least one inorganic substance selected from silicon dioxide, aluminum oxide, titanium oxide, zirconium oxide, tantalum oxide, yttrium oxide, and niobium oxide and an organosilicon compound that is a liquid at normal temperature and at atmospheric pressure and/or an organic compound not containing silicon that is a liquid at normal temperature and at atmospheric pressure as vapor deposition raw materials.
