Abstract
A microscope includes a switching mechanism which has a plurality of lens units, and which inserts a selected lens unit of the plurality of lens units into an observation light path and disposes the non-selected other lens units outside the observation light path. A control unit controls a movement speed of a stage, onto which a sample is placed, in an optical axis direction according to an observation power of the selected lens unit inserted into the observation light path. The plurality of lens units include: (i) a plurality of fixed-power lens units which are lens units including a combination of imaging lenses and objective lenses, and whose observation powers when observing the sample mutually differ, and (ii) a zoom lens unit which has a continuously changeable observation power.
