Abstract

An apparatus for dental confocal imaging comprises an illumination module for generating an array of light beams, an optics system for confocal focusing of the array of light beams and a probe head with a light-guiding part having an entrance face and an exit face. The illumination module, the optics system and the probe head are arranged such that the array of light beams from the illumination module passes through the optics system, enters the light-guiding part via the entrance face and exits the light-guiding part via the exit face. The optics system is configured such that, after having passed through the optics system, the outermost marginal rays of the outermost light beams with respect to the optical axis of the optics system are parallel or divergent to the optical axis.
