Abstract
A dental imaging and illumination device. The device has an optical interface for emitting light from the device and for receiving light into the device. The device has a light source, a camera, a beam splitter and a color reference. The color reference and the light source are optically coupled via an optical path so that the light source can illuminate the color reference. This optical path bypasses the beam splitter. The device facilitates color measuring particularly in the field of dentistry.
