Abstract
The invention relates to an optical unit for duodenoscopes, wherein the light reflected along the length of direction Z by an illuminated object is guided in the direction Z through an optical system in an essentially perpendicular manner in relation to a CCD-chip. In relation to prior art, the optical unit is constructed in a simpler manner, is smaller, and is more resistant to leakages.
Claims8
An optical unit for the distal head of lateral-viewing duodenoscopes, having
- a) an optical system for optical preparation of light signals, wherein the light signals
- a1) enter the optical system from outside the head in an axial direction and
- a2) run through the optical system essentially in this direction, and having
- b) a CCD-chip alongside the optical system for transforming the light signals that land on a surface of the CCD-chip, distinguished in that
- c) the length of direction passes through the surface essentially perpendicularly.
