ABSTRACT:
Assembly of interchangeable autofocus light guides of varying diameter for a dental curing light apparatus to provide maximum power density independently of the selection of light guide. Each light guide has an optic rod of a preselected diameter and a proximal end axially spaced from the focal spot, such that radiant energy incident upon the proximal end corresponds to a predetermined surface area matched to said preselected diameter. Each optic rod also has a head of common diameter for interchangeable insertion into the light-curing apparatus.
