ABSTRACT:
The invention provides a confocal microscope comprising a light source; a light scanning unit; an array device; a line-beam generating unit for imaging illumination light in the form of a straight line extending, on the array device, in a direction intersecting the scanning direction of the light scanning unit; an objective lens for imaging the illumination light reflected or transmitted at the array device on a specimen; a beamsplitter, between the array device and the light scanning unit, for splitting off from the illumination light detection light from the specimen; a two-dimensional image-acquisition unit for acquiring the split off detection light; and a control unit for controlling the light scanning unit and the array device, wherein the array device is disposed in an optically conjugate positional relationship with a focal plane of the objective lens, and the control unit performs control so as to synchronize the light scanning unit and the array device.
