<P>PROBLEM TO BE SOLVED: To provide an imaging optical system capable of observing an object from an arbitrary angle, and to provide a microscope device including the imaging optical system. <P>SOLUTION: An imaging optical system 5 for use in a microscope device 100 forms an image of an object by an objective lens 1 and an observation optical system 2. The observation optical system 2 includes a plurality of lens groups, at least two lens groups of the plurality of lens groups are configured to be continuously movable in the orthogonal direction of the optical axis of the objective lens 1 respectively. According to the orthogonal moving amounts of at least the two lens groups, a region of a luminous flux passing through the observation optical system 2 moves in a plane including the exit pupil of the objective lens 1, in relative to the exit pupil by a predetermined amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
