1. A fluorescence microscope having an illuminating system for irradiating an excitation light onto a sample for observation
of a fluorescent image of the sample, comprising:
(a) a transmissive illumination light source, which is arranged above a stage for placing the sample and said transmissive
illumination light source is arranged facing a horizontal direction;
(b) a tilt mirror, which reflects light from the transmissive illumination source and illuminates the sample on the stage
from above;
(c) a transmissive illumination optical unit including at least the tilt mirror is disposed so as to move in a direction in
which said transmissive illumination optical unit is brought away from the stage from a normal position; and
(d) a sample cover for shielding a light from said stage, wherein said sample cover is displaceable downward so as to expose
said stage.
