A sterile covering for an optical device comprises a window element and a shell. The shell is attached to the window element, the shell having an opening closed by the window element. A system comprises an optical device and a sterile covering.

Sterile covering for an optical device

An endoscope having two entry lenses, which are arranged spaced from each other and the fields of view of which overlap, and having guiding devices. The entry lenses are spaced so far apart from each other that the outer edges thereof protrude beyond the cross-sectional area of the guiding devices, and a lens displacing the axis beam is inserted between one entry lens and the guiding devices. A method for the use of the endoscope.

The method for reconstructing the three-dimensional shape of the surface () of at least a portion of an ear canal () and/or of a concha comprises&#x2014;for each of a multitude of points () on said surface ()&#x2014;the step of using a chromatic coded distance measurement technique for determining a distance value () representative of a distance to said point (); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (). The system for reconstructing the three-dimensional shape of the surface () of at least a portion of an ear canal () and/or of a concha, comprises a distance measurement unit for determining&#x2014;by means of a chromatic coded distance measurement technique and for each of a multitude of points () on said surface ()&#x2014;a distance value () representative of a distance to said point; and a reconstructing unit () operationally connected to said distance measurement unit for reconstructing said three-dimensional shape based on said multitude of distance values ().

Disclosed is a measuring instrument for determining geometric properties of a profiled element. Said measuring instrument comprises:&#x2014;a device that generates at least one first light beam () and a second light beam (), the direction of radiation of the first light beam being different from the direction of radiation of the second light beam;&#x2014;a retro-reflecting surface () which is arranged in such a way relative to the light source that at least some of both light beams is incident on the retro-reflecting surface; and&#x2014;a recording device () which can determine, across the transversal extension thereof, the light intensity distribution of at least some of the reflected light beam of the first light beam and at least some of the reflected light beam of the second light beam, the first light beam being reflected by the retro-reflecting surface and the second light beam being reflected by the/a retro-reflecting surface.
