PROBLEM TO BE SOLVED: To prevent decoloration of fluorescent light by performing a focusing operation in a short time.SOLUTION: A specimen analyzer comprises a specimen stage supporting a test piece, a light source, a plurality of divided sensors for detecting light generated in the test piece, an irradiation optical system which makes light emitted from the light source incident from an obliquely upper side to the test piece, a detection optical system which guides light generated in the test piece to the sensors, a lifting device which moves the specimen stage to change an interval between the test piece and the sensors, a control section, and a defocus characteristic data storage table in which characteristic data acquired from output signals of the sensors are made correspondent to the amount of correction that the lifting device should perform. The control section acquires characteristic data from output signals of the sensors and changes the interval by the lifting device on the basis of the correction amount corresponding to the data. |
