摘要：PROBLEM TO BE SOLVED: To provide a living thing microscope that allows automatic focusing or semi-automatic focusing on an observation target placed on the back of a cover glass. SOLUTION: A focus error detecting optical system 20 has such an optical parameter that a focus lead-in width corresponding to a focus error signal has a value at which focus on the surface 52a of the cover glass 52 and that on back 52b of the cover glass are separated and detectable. Based on the focus error signal obtained by the focus error detecting optical system 20, a control circuit 3 brings the focus fc of an observing optical system 10 into a focusing position, the reference of which is the back 52b of the cover glass 52.
