PURPOSE: To manufacture a non-spherical glass lens simply, by a method wherein a mold, wherein a heat medium is fluidized freely, and a controller, capable of controlling a light source and the temperature of the heat medium, are provided.
CONSTITUTION: In a mold 1, the center of a glass lense 3 can be determined by a bell clamp structure and a heat medium can be flown into an insert 4 having a non-spherical configuration, while a light source 2 for photo- polymerizatoin is attached to the mold. The proper amount of a mixed liquid 5 (a polymerization initiating agent, an ultraviolet ray absorbing agent and a prepolymer) is poured onto the insert 4. Next, a glass lense, whose surface is treated with a silane coupling agent previously, is put on it. Then, the center and the center thickness of the glass lense are determined by descending the mold from the upper side thereof. Subsequently, light is emitted from the light source 2 to photo-set the mixed liquid. Heat energy, generated by photo-polymerization, is cooled by flowing the heat medium around the mold 1 and the insert 4 by employing a controller 8 and a valve unit 7. Thus resin is photo- polymerized on the surface of the spherical galss lense, whereby a non-spherical composite lense may be molded simply.
