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 chief rays of the light before entering the probe head are divergent to each other, wherein an angle defined by a marginal ray of an outermost beam of the light is complementary to an angle defined by an extreme off-axis chief ray of the light with respect to the optical axis.

Abstract: An apparatus for intraoral scanning comprises an elongate handheld wand comprising a probe at a distal end, one or more light projectors, and two or more cameras. Each light projector comprises at least one light source configured to generate light and a pattern generating optical element configured to generate a pattern of light when the light is transmitted through the pattern generating optical element. Each camera comprises a camera sensor and one or more lenses and is configured to capture a plurality of images that depict at least a portion of the projected pattern of light on an intraoral surface, wherein each camera is configured to focus at an object focal plane that is located between about 1 mm and about 30 mm from a lens of the one or more lenses that is farthest from the camera sensor.

Abstract: An apparatus for dental imaging comprises a light source for generating light, an optics system for focusing the light, and a light-guiding part having an entrance face and an exit face. The light source, the optics system and the light-guiding part are arranged such that the light 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, upon entering the light-guiding part, 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.

Abstract: An apparatus for intraoral scanning includes an elongate handheld wand that has a probe. One or more light projectors and two or more cameras are disposed within the probe. The light projectors each has a pattern generating optical element, which may use diffraction or refraction to form a light pattern. Each camera may be configured to focus between 1 mm and 30 mm from a lens that is farthest from the camera sensor. Other applications are also described.

Abstract: A protective sleeve comprises a housing configured to fit over a portion of an intraoral scanning device and protect the intraoral scanning device from an external environment. The intraoral scanning device comprises a first aperture for transmission of optical signals, the housing defines a second aperture for transmission of the optical signals, and the second aperture is aligned with the first aperture when the housing is fit over the portion. The protective housing comprises one or more supports attached to the housing and a transparent element secured by the one or more supports and aligned with the second aperture. The transparent element is further aligned with a defogging element of the intraoral scanning device when the housing is fit over the portion, and an external surface of the transparent element is to receive heat generated by the defogging element to prevent fogging of the transparent element.

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.
