FLUORESCENCE SPECTRAL ANALYZER

摘要

A fluorescence spectral analyzer (100) comprising an exciting optical system (110), an exciting light control unit (130), a fluorescence detection unit (140), a signal processing unit (150) and an operation unit (160). The exciting optical system (110) has an exciting light irradiation unit (120) for generating an exciting light, and the exciting light control unit (130) controls the exciting light irradiation unit (120) so that a sample (S) is irradiated with exciting lights having different wavelengths exclusively and at different timings. The exciting light irradiation unit (120) applies exciting lights having different wavelengths to one portion on the sample (S). The fluorescence detection unit (140) detects fluorescence generated from the sample (S) according to the irradiation of an exciting light. The signal processing unit (150) processes a signal reflecting a fluorescence intensity obtained at the fluorescence detection unit (140). The operation unit (160) performs a correlation analysis on fluorescence fluctuations for respective different wavelengths based on a change in the wavelength of an exciting light applied to the sample (S) by the exciting light control unit (130) and the detection results by the fluorescence detection unit (140).
