Abstract

PURPOSE:To form a lens of a free diameter with good dimensional accuracy accurately, by pouring a resin in a lens mold, covering the resin with a glass plate in such a way that the surface of the lens mold is not brought into contact with one face of the glass plate, irradiating the resin with an ultraviolet ray and curing the resin while the resin adheres to both surfaces of the mold and the glass plate and the mold is kept in such a state that the mold does not collapse. CONSTITUTION:After an ultraviolet ray curable resin 1 is poured, when the resin is covered with a glass plate 2, both surfaces of the glass plate 2 and a lens mold 3 are positioned in a separated state each other in such an extent that the surface of the resin 1 rising due to the surface tension adheres to the glass surface, so that the glass plate 2 can not be brought into contact with the surface of the lens mold 3. Then, in such state the resin 1 is irradiated with ultraviolet ray 4 and thereby cured. The resin 1 is placed in the lens mold 3 in such a state that it rises due to the surface tension and is covered with the glass plate 2 in such a state that the glass plate 2 sinks about several hundreds microns below the surface of the resin. No excess resin is therefore produced and it is possible to form a lens on the glass plate 2 just as it follows the shape of the lens mold 3 and to simplify the operation. As it is possible to produce a lens without any limitation on the lens size caused by the limitation of the size of the glass or the size of the facilities such as the oven and the like, the productivity is remarkably improved.
