Abstract
A confocal microscope includes an objective lens for converging light which is emitted from a light source to a sample, a scanning mechanism for relatively scanning the sample with the light converged to the sample, and a plurality of confocal diaphragm apertures that are arranged at positions optically conjugate to the light-gathering position of the objective lens and have different diaphragm diameters. The confocal microscope further includes a plurality of photodetectors for detecting the intensities of lights respectively transmitting through the confocal diaphragm apertures, and a weighting/combining arithmetic processing unit for combining signals output from the photodetectors after weighting the signals.
