OPTICAL UNIT FOR LATERAL VIEWING DUODENOSCOPES

摘要

The invention relates to an optical unit for doudenoscopes, wherein the light reflected along the length of direction Z by an illuminated object is guided in said direction through an optical system in an essentially perpendicular manner in relation to a CCD-chip. In relation to prior art, said optical unit is constructed in a simpler manner, is smaller and is more resistant to leakages.
