Abstract

A hand-operated polymerizer for the polymerization of synthetic materials, such as dental plastics. The polymerizer has a housing in which a light source and a fan are disposed, and which includes a light-emitting opening for emitting the light generated by the light source. The housing contains openings for permitting cooling air to enter the housing and for allowing heated air to exit the housing. In order to prevent the operator of the polymerizer from being impaired by heated air when operating the polymerizer, at least one air-conducting member is provided, wherein the position of the air-conducting member is changeable relative to the housing.
