ABSTRACT:
A microscope system comprises a light guiding optical system20containing an objective lens21and a beam splitter25for splitting an optical image of a sample S to a first optical path and a second optical path, a photodetector31disposed on the first optical path used to acquire an image of the sample S, and a CCD camera32disposed on the second optical path for acquiring a two-dimensional image for focus control. The camera32is disposed being inclined at an angle of θ with respect to the optical path so that the optical path length in the light guiding optical system20varies along the z-axis direction. The image acquired by the camera32is analyzed by a focus controller37, and the focal point for image pickup with respect to the sample S is controlled on the basis of the analysis result. Accordingly, there can be implemented a microscope system in which image acquisition of the sample and focus control for image pickup can be simultaneously performed.
