Abstract: An endoscope system for imaging a sample, an inner part of a patient, or an organ with an imaging device includes an endoscope tube with a proximal end and a distal end configured to mount the imaging device. A handle at the endoscope tube proximal end is configured to move the endoscope tube rotationally. An interface is configured to removably attach the endoscope tube to the handle and to rotate the endoscope tube around a main axis relative to the handle without restriction.

Abstract: A dental measuring device for three-dimensional measurement of a patient's teeth having projection means with a projection unit 8 to project a measuring structure onto a tooth to be examined. The device also has a camera to capture a measuring structure projected onto the tooth. According to the present invention, the projection unit has at least one UV light source, wherein the power output from the UV light source is selected or can be selected such that light-curing dental materials can be cured by the effect of the UV light, in such a way that the device can be used or is used for curing light-curing dental materials.

Abstract: A contactless dental device for determining tooth colors includes illuminating means for illuminating with ambient illumination light a tooth to be examined. At least one color sensor for acquisition and spectral examination of light reflected by the tooth is inventively provided, wherein filtering means are associated with the color sensor for at least partial separation of a signal component originating from the illumination light from the signal component originating from the ambient light. Evaluating means for determining the tooth color based on the signal component originating from the illumination light are disposed downstream of the filtering means.

Abstract: In a method for operating of a dental camera to which having an illumination device with at least one light source for illuminating a tooth under examination with illuminating light, and also an image processing device are allocated, at least one first image and one second image are recorded, wherein between the first and the second image at least one property feature of the illuminating light is varied, preferably its angle of incidence onto the tooth, and wherein the images are compared by the image processing device in order to determine any overexposure.
