Abstract
An apparatus for treating dental prosthetic parts includes a lamp, a reflector, a filter and an optical wave guide to project radiation of a selected spectral range onto a location of treatment. When an object is placed at this location, it actuates an infrared proximity switch which turns on the lamp for at least a predetermined period of time. A protective pane is disposed in front of the lamp and location of treatment which absorbs the selected spectral range but transmits other visible light to avoid glaring of an operator. The portion of the apparatus beneath the location of treatment includes a plate which is also absorptive in the selected spectral range to avoid disturbing reflections, and is replaceable since it may become contaminated by dental material dropping onto it and curing there.
