Abstract
The present invention relates to an endoscope comprising a deflection system for a visual angle of up to 30 degrees which comprises reflective deflection elements. The inventive endoscope is characterized in that the beams which form the image are reflected more than twice. This enables visual angles of less than 30 degrees to be used, without any reduction in the image quality.
Claims16
Endoscope with a relay system defining an endoscope axis, and a deflection system for deflecting a beam entering the endoscope at an angle greater than 0 degrees and less than or equal to 30 degrees with respect to said endoscope axis, while the deflection system contains reflective deflection elements provided with reflecting surfaces, and the reflecting surfaces are arranged so that the beams deflected into said endoscope axis are reflected more than twice;
- at least one reflecting surface is used in transmission as well as in reflection;
- and
- wherein said endoscope axis is generally parallel to a longitudinal axis of said endoscope.
