Abstract
A microscope has an objective optical system coupled to an observation optical system with parallel optical axes. A stage, which holds a sample, rectilinearly moves in a direction toward and away from the observation optical axis, which is perpendicular to the plane of the stage. The objective optical system rectilinearly moves in a direction perpendicular to the movement of the stage. The microscope thus permits viewing of a large sample with a small stroke of the stage, whereby a compact and lightweight structure may be achieved.
