Abstract
A device for curing a photosensitive dental composition curable by way of irradiation with light of predetermined wavelength includes a power supply; and a radiation source coupled to the power supply and powered thereby, the radiation source having a radiation output and including an axial array of light emitting diodes. The light emitting diodes are mounted about an assembly axis defined thereby at a plurality of axial distances from said radiation output of the radiation source and being further characterized in that the plurality of light emitting diodes are directed along a plurality of divergent paths such that a position insensitive optical field is generated for curing the dental composition.
