An optical assembly for an endoscope, the optical assembly including: an objective tube; and at least one optical element held in the objective tube; wherein the objective tube comprises at least one region acting as a clamping mount for the at least one optical element, and the at least one region of the objective tube acting as the clamping mount is at least sectionally formed of a shape-memory material.

An endoscope having an elongate shaft and a system tube, which extends inside the shaft and in which an image carrier is arranged, the system tube is held in an axial direction of the shaft by means of at least one resilient latching element, and a method for producing such an endoscope and to a latching element for such an endoscope.

A method comprises obtaining reference data about a 3D calibration object, the reference data comprising known coordinates for a plurality of points on the object, and obtaining measurement data comprising measurements for the plurality of points on the object, the measurement data having been generated based on scanning of the object by an uncalibrated intraoral scanner. The method comprises comparing the measurement data to the reference data to determine differences therebetween and applying the determined differences between the measurement data and the reference data for the plurality of points to a function to generate a compensation model that compensates for one or more inaccuracies of the intraoral scanner. The compensation model is then stored, wherein the compensation model causes the intraoral scanner to be a calibrated intraoral scanner and is usable to correct measurement errors of the intraoral scanner caused by the one or more inaccuracies of the intraoral scanner.

Improved fluoresced imaging (FI) and other sensor data imaging processes, devices, and systems are provided to enhance use of endoscopes with FI and visible light capabilities. A first optical device is provided for endoscopy imaging in a white light and a fluoresced light mode with an image sensor assembly including one or more image sensors. A mechanism in the first optical device to automatically adjust the focus of the first optical device wherein the automatic focus adjustment compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive or diffractive properties of the optical materials or optical design employed in the construction of the first or second optical devices, or both. Adjustment mechanisms are provided using liquid lenses or repositioning sensors. The design may be integrated with a scope or detachable.
