Abstract:
The invention relates to an endoscope used for lighting and visualizing the fields of an object in cavities. The inventive endoscope comprises a lighting unit and an image transmitting system provided with an optical lens on the distal side thereof and with an optical eyepiece or a filming unit which are used as an observation system on the proximal side thereof. Said endoscope is characterized in that an optical dividing element for complementary light polarization or for wavelength bands and the complementary polarization is inserted between the lighting unit, the image transmitting system, and the visualizing system in such a way that the light emitted by the lighting unit can be injected into the image transmitting system. The dividing element for the complementary light polarization is combined with a quarter-wave plate which is arranged before the lens on the distal side thereof.
