Abstract
A system and method for achieving partial polymerization of a photoreactive resin include: (i) light source means for providing light energy to the photoreactive resin, the light source means having an intensity; (ii) timing means for causing the light source means to provide light energy to the photoreactive resin for an illumination time, during which the light source means provides light energy to the photoreactive resin, the timing means selectively operable in a plurality of different time increments, thereby allowing fine tuning of the total amount of light energy provided to the photoreactive resin; and (iii) power supply means electrically coupled to the light source means and the timing means for supplying electrical power to the light source means and the timing means. In one embodiment, the system is programmed to automatically achieve a constant total light energy output despite variations in the intensity of the light source means. The system may also pulsate and is operable in a full cure and partial cure mode.
