ABSTRACT:
A microscope includes a light source, an objective lens for converging light emitted from the light source onto a sample, and an optical detector for detecting either light from the sample via a confocal point diaphragm or light from the sample which does not pass through the confocal point diaphragm. A range of a focusing point is detected in accordance with the light which does not pass through the confocal diaphragm, and the focusing point is then detected in accordance with the light detected via the confocal point diaphragm in the detected range of the focusing point.
