Title:
STEREO-ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2010/079817
Kind Code:
A1
Abstract:
A pair of left and right rod lenses (19) is disposed in the insertion part (10) of a stereo-endoscope (3), and an objective optical system (18), consisting of a stationary lens (22) and a moveable lens (23), is disposed at the tip thereof. The moveable lens (23) is moved by a motor (24) to change the distance to the stationary lens (22). Consequently, the focal length of the objective optical system (18) can be changed, whereby sites with different focal points can be observed without shifting the stereo-endoscope (3) forward and back as a whole.
