Abstract
A reflector for use in a dental, medical or other lighting device wherein light from a light source is reflected thereby in a predetermined pattern for illumination of a desired zone. The reflector is formed of a glass substrate of predetermined shape for reflecting light in a predetermined pattern and has a dichroic coating on the front surface for reflecting a substantial portion of visible light and for allowing infrared and other undesirable energy along with some unreflected visible light to pass therethrough so that cool light only is reflected and a diffuser coating on the rear surface for diffusing light passing through the glass substrate to reduce undesirable glare from the rear of the reflector. The diffuser coating is preferably a ceramic frit.
