ABSTRACT:
A light curing gun for dental filling material includes a conical light concentrator element and a water filed chamber between the light source and the concentrator element. The water increases the collection of light as well as cooling the concentrator and filtering out light in the infrared portion of the spectrum. A water cooling jacket may also be provided around the light source and may be coupled to the water window so that water can be circulated through both the window and the water jacket.
