Abstract
A fluorescent microscope includes a laser scanning unit having a stage for supporting a fluorescent sample, a laser beam generator and a beam scanning unit for causing a laser beam from the generator to spot scan a sample to cause fluorescence generated by multi-photon absorption. A first detector detects fluorescence emitted from a side of the sample on which the laser beam is incident to output a first signal corresponding to detected fluorescence. A second detector detects fluorescence emitted from a side of the sample from which the laser beam, having been transmitted through the sample, is emitted from the sample. The second detector produces a second signal corresponding to the detected fluorescence. The first and second signals are summed and amplified. A display is provided for a microscopic image of the sample in synchronization with the scanning of the laser beam, based on the amplified summed signals.
