Abstract
A plurality of optical members (lenses) for use in ultraviolet region are mutually stuck. A fluorine-based organic compound (for example, fluorine-based oil) is provided between them. The periphery of the optical members is sealed with a sealant. As the sealant, an adhesive fluorine resin, for example, a soluble fluorine resin is used.
Claims4
