Abstract: An optics arrangement for an endoscope is provided. The optics arrangement images an object situated in front of its distal end to the proximal end of the optics arrangement along a principal beam path having an optical axis. The optics arrangement is designed both for light from the visible spectrum and for light from the near infrared. The optics arrangement includes an aperture stop with a reflection layer in the principal beam path. The reflection layer reflects light from the visible spectrum and transmits light from the near infrared. The reflection layer is inclined in relation to the optical axis.

Abstract: A magazine for accommodating pellets for use in an injector includes a barrel comprising a hollow cylindrical compartment with an open front end and an open rear end. The cross-section of the compartment is selected to accommodate a pellet. The cross section of the rear end is smaller than the accommodated pellet so that it cannot be extracted from the rear end of the compartment. The magazine further includes a cover for closing the front end, including a dispensing opening which, in the closed state, is positioned in front of the front end and has a cross-section selected such that the pellet can pass through the dispensing opening. At least one bar projecting into the dispensing opening prevents the pellet from accidentally falling out, and when subjected to a predetermined force, can be bent outwards such that the pellet can be delivered through the dispensing opening.

Abstract: A bottle holder for a syringe includes a stop surface, a piercing hollow spike protruding beyond the stop surface, a guideway, and a first and a second clamping element. Each clamping element includes a through-hole and is moveable back and forth between an insertion position and a clamping position. When the clamping elements are in the insertion position, a neck of the bottle can be moved through the through-holes until the front end of the bottle abuts against the stop surface such that the piercing hollow spike pierces a film at the front end of the bottle. At least one of the clamping elements in its clamping position presses against the neck of the bottle in order to clamp the bottle in the holder.

Abstract: An optical system for an endoscope includes an objective and a reversal system arranged after the objective. The reversal system includes at least one reversal stage for projecting the distal intermediate image as a proximal intermediate image into a proximal intermediate image plane. The reversal system imprints on the proximal intermediate image a first longitudinal chromatic aberration referred to a predetermined wavelength from the visible spectrum and a predetermined wavelength from the near infrared range. The objective imprints on the distal intermediate image a second longitudinal chromatic aberration referred to the predetermined wavelength from the visible spectrum and the predetermined wavelength from the near infrared range. The second longitudinal chromatic aberration has the opposite sign relative to the first longitudinal chromatic aberration, which reduces the longitudinal chromatic aberration caused by the reversal system in the proximal intermediate image.

Abstract: An endoscope includes a main unit and a shaft, connected to the main unit, which extends along a longitudinal axis. The shaft includes a jacket tube, an inner tube for receiving an objective lens, and a bundle of fibre-optic light guides. The inner tube includes, at a distal end, an inner tube head which includes a first bearing section and a second bearing section, which is connected to the first bearing section by a connecting element. The first bearing section includes a first bearing surface, against which the bundle of fibre-optic light guides abuts, and the second bearing section includes a second bearing surface, against which the bundle of fibre-optic light guides abuts, wherein, to align the bundle of fibre-optic light guides at the distal end, an area of the first bearing surface and/or an area of the second bearing surface run non-parallel to the longitudinal axis.

Abstract: An endoscope is provided with a main part, an endoscope shaft and an imaging lens system. An imaging lens system includes a correction module, which comprises a splitter unit and a superimposition unit.

The superimposition unit superimposes the light from the two partial beam paths and guides it into a second beam path, coaxial with the first beam path. The optical path lengths of the two partial beam paths for the light from the visible spectrum and the light from the near infrared range are selected such that they are different.
