Abstract
An intraoral scanner comprises a housing, a light source for generating light, an optics system for focusing the light, a detector for detecting returning light reflected off an intraoral object, and a focus shifting mechanism configured to shift a focal plane of the optics system. The optics system is configured such that, after having passed through the optics system, 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.
