Abstract

Abstract A microscope including a base frame, a stage provided on or over the base frame, and a file page placed on the stage and adapted for supporting a plurality of samples. An arm extends from the base frame up to a place over the stage. A magnifying optical system has an optical axis directed in a direction orthogonal to the stage, and an illuminating optical system is provided on the axis of the magnifying optical system at a place spaced from the stage.
