Abstract
The invention provides an apparatus and method for delivering laser radiation to a substrate (20,120) involving a laser radiation source (1), delivery means (2) to transmit the laser radiation from the source, a delivery head (3) to direct the laser radiation from the delivery means onto the substrate. The delivery head has isolation means to isolate a selected target area from its surroundings by substantially preventing escape of laser radiation, and viewing means are provided to enable an operator to view the selected target area. The apparatus is specifically for application in curing restorative or prophylactic tooth coatings, such as vitreous dental compositions or sol gels.
