Abstract:
1. An optical microscope, comprising: a laser light source; a first scanner deflecting a light beam from the light source and scanning in a first direction; an objective lens condensing the light beam deflected by the first scanner on a sample; a second scanner changing a position of the light beam scanned by the first scanner relative to the sample and scanning in a second direction; a beam splitter provided in an optical path between the first scanner and the sample and separating an outgoing light from the incident light beam incident on the sample, the outgoing light exits from the sample toward the objective lens with a wavelength different from a wavelength of the incident light beam incident on the sample from the laser light source; a spectroscope having an entrance slit extending along a direction corresponding to the first direction on an incident side of the spectroscope where the outgoing light separated by the beam splitter is focused and incident; and a two-dimensional array photodetector detecting the outgoing light dispersed by the spectroscope, wherein an exposure period of the two-dimensional array photodetector is an integral multiple of a scanning period of the first scanner.
