ABSTRACT:
A multi-function dental operating light source comprises a plurality of optical filters and reflectors mounted upon a turntable at spaced locations around the periphery thereof, the turntable being rotatable to different predetermined positions relative to a collimated light source to produce selectable different modes of light delivery. The optical filters are adapted respectively to produce light beams for shade-matching, no-cure to prevent polymerization of light-curable resins when exposed to said light for observation purposes, a photocuring light beam, and beams for oral illumination and transillumination. The photocuring light is preferably developed by condensing the collimated light through a light-condensing cone or through an optical condensing system, the condensed light being delivered either directly from the condenser output or through a light pipe arrangement.
