Title:
STEREOSCOPIC MICROSCOPE
Document Type and Number:
WIPO Patent Application WO/2009/131243
Kind Code:
A1
Abstract:
A stereoscopic microscope (100) provided with a pair of right and left observation optical systems (I) and a pair of right and left illumination optical systems (S) is characterized in that the observation optical systems (I) have a variable magnification optical system (11) and an objective lens (7), the illumination optical systems (S) have an illumination light deflection member (5) arranged in an optical path of the observation optical systems and a variable magnification illumination lens group (3) that can make a magnification of a light source image formed at an entrance pupil of the variable magnification optical system changeable in accordance with a magnification of the variable magnification optical system, the illumination light deflection member (5) is arranged between the variable magnification optical system (11) and the objective lens (7), thereby providing a stereoscopic microscope that can irradiate suitable illumination light to a sample in accordance with a magnification operation of an observation optical system.
