Abstract
A photopolymerization for dental use composed of a light of sources emitting at least visible light and infrared light transparent cells charged with coolant disposed to the emission side of said light source, whereby absorb infrared light; and a board for mounting a formed article which is composed of materials for a pattern made of photopolymerizable resin, impinging the light thereon from the light source after transmitting through said cells, wherein the tranparent cell is composed of disc-like shaped main body having a hollow space therein which is formed integrally with heat resistant glass; and two glass pipes for circulation of coolant which is disposed to the cell main body communicated to the hollow space.
