Claim Text:
1. A 3D scanner for recording topographic characteristics of a surface of at least part of a body orifice of a patient, where the 3D scanner comprises: a main body comprising a mounting portion; a tip configured to be mounted onto and un-mounted from said mounting portion, where said tip is configured for being brought into proximity of said body orifice surface when recording said topographic characteristics such that at least one optical element of the tip is at least partly exposed to the environment in the body orifice during said recording; a heater system for heating said optical element, said heater system comprising a source of electromagnetic energy and a receptive element configured for receiving the electromagnetic energy and converting the electromagnetic energy into heat; and a control system configured to control heating of the optical element; where the tip is configured to be sterilized when un-mounted from the main body of the 3D scanner such that the tip subsequently can be reused, where said heater system comprises one or more elements configured for transferring the electromagnetic energy from the source to the receptive element, where the optical element comprises a mirror and the receptive element comprises a resistive element arranged behind the mirror, and where the elements configured for transferring the electromagnetic energy are configured for transferring the electromagnetic energy from the main body to the receptive element.
