Abstract

An apparatus for dental imaging comprises a light source for generating light, an optics system for focusing the light, and a probe head. The light source, the optics system and the probe head are arranged such that the light passes through the optics system, passes through the probe head, and exits the probe head. The optics system is configured such that, upon entering the probe head, an outermost chief ray of the light with respect to an optical axis of the optics system is divergent to the optical axis and an outermost marginal ray of the light with respect to the optical axis is parallel or divergent to the optical axis.
