    Abstract: The present disclosure relates generally to thermal management of a scanner, in particular a cooling system for a scanner. More specifically the present disclosure relates to a scanner wherein the cooling system is integrated, in particular a wireless intraoral scanner with integrated cooling. The present disclosure further relates to method for cooling the scanner. One embodiment relates to an intraoral scanner for scanning a dental object, comprising an outer shell housing defining a longitudinal axis of the scanner, the outer shell housing accommodating electronic components generating heat during use, and a cooling system for removing heat from the electronic components, the cooling system comprising a heat exchanger, such as a heat sink, and a fan.

    Abstract: Disclosed is fixation by means of any type of adhesive of an assembly consisting of two or more sub-parts internally joined rigid together, e.g. a cemented doublet, or - as detailed in an example - a beam splitter. It is often beneficial to constrain the fixation to only one of the subparts in order to prevent either optical degradation of the performance or even physical damages due to thermal stress. The invention consists in limiting the adhesive area by adding a patterned - non adhesive - element to part of the interface.

    Abstract: An intra-oral handheld 3D optical scanner includes an illumination module configured to generate an illumination signal to illuminate a dental object, and an image sensor configured to obtain data in response to the illumination of the dental object. The data is configured to be used to generate a 3D dental model of the dental object. The scanner also includes a lens housing comprising an optical lens that is configured to direct the illuminating signal towards the dental object, and a drive comprising a shaft that is configured to rotate around a rotation axis. The scanner also includes a guide extending continuously along at least a part of a length of the shaft and a spring, arranged intermediate between the lens housing and the guide, configured to exert a spring force towards the guide.
