Abstract
An irradiation unit () projects excitation light (LB) having an asymmetric shape with respect to an optical axis (A, A). An objective lens () concentrates the excitation light (LB) at a measurement-target member () including a glass member (C,A) and a measurement-target region (B). The detection unit () includes at least one or more light-receiving units () that receive fluorescence emitted from the measurement-target region (B) in response to the excitation light (LB), and outputs a fluorescence signal indicating intensity values of fluorescence received by the respective light-receiving units (). The movement control unit (C) includes a derivation unit (B) that derives a movement amount and a movement direction of at least one of the objective lens () or the measurement-target member () on the basis of the fluorescence signal, and moves at least one of the objective lens () or the measurement-target member () by the derived movement amount in the derived movement direction.
