Abstract
A microscope having little damage such as deformation, discoloration or the like given to a sample is disclosed. This microscope comprises an illuminance reducing unit for reducing illuminance of an illumination light on the sample. Assuming that a time width where illuminance is at a level enough for displaying an image of the sample is TF, a time width where illuminance is lower than the level enough for displaying an image of the sample is TN, and a value &agr; is as follows:&agr;=TF/(TF+TN)the value &agr; is changed according to a velocity of a stage or the like. A monitor displays a still picture of the sample for a period of TN, the still picture being one before the time width TN.
