ABSTRACT:
A confocal scanning microscope comprises a specimen support, a light source, a light-projecting optical system, a light-receiving optical system, a light detector, a mechanism for two-dimensionally scanning the specimen with the light spot, an image reproduction means, a focus monitoring means which monitors the state of convergence of the light spot on the specimen, and a signal output regulating means for selectively forwarding the signal output by the light detector to the image reproducing means only when the focus monitoring means detects that the light spot is properly focused on the specimen.
