Abstract: The present disclosure relates to an intraoral scanning device including a light source configured for emitting light; a beam splitter configured for outputting linearly polarized light of a predefined orientation, wherein the beam splitter is arranged such that light from the light source is transmitted through the beam splitter; an image sensor configured for acquiring one or more images; and a light absorbing unit for minimizing stray light on the image sensor, said light absorbing unit arranged on a surface of the beam splitter. The present disclosure further relates to an optical system for an intraoral scanning device, said optical system configured for minimizing stray light in the system.

Abstract: An intraoral scanning system that includes a housing and a sleeve. The housing includes optical components, a head, and a defogging unit that includes a heating unit. The head includes a primary aperture and is configured to be inserted into an oral cavity of a patient. The sleeve includes a secondary optical component arranged at a secondary aperture that is configured to be positioned in alignment with the primary aperture when the sleeve is coupled with the housing. The heating unit is configured to generate heat in response to application of electrical power to the heating unit. When the sleeve is coupled with the housing, the secondary optical component is configured to be arranged such that the generated heat is transferred from the heating unit to the secondary optical component through thermal conduction between the heating unit and secondary optical component.
