Optical unit for lateral viewing duodenoscopes

摘要

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.
