ABSTRACT:
A laser scanning microscope which focuses light beams from a laser beam source to a sample by means of an objective lens and detects transmission light from the sample, reflection light, or fluorescence generated from the sample, includes an observation laser scanning optical system which irradiates coherent light from one side of the sample and which carries out scanning the sample, a stimulation laser scanning optical system which irradiates coherent light from an opposite side across the sample and which carries out scanning the sample, an observation light detector provided to be branched from the observation laser scanning optical system, and a light invasion preventing section which prevents the coherent light irradiated from the stimulation laser scanning optical system from invading the observation light detector.
