Patent ID: 8680484

Claim:
A fluorescence detecting apparatus which irradiates light for fluorescence measurement to a substrate on which biologically relevant molecules are captured, collects fluorescence generated therefrom, forms an image of the collected fluorescence on a two-dimensional detector, and causes the two-dimensional detector to perform fluorescence detection, the fluorescence detecting apparatus comprising: a substrate including a plurality of regions in which molecules are to be captured, the regions being disposed at lattice point positions of a lattice structure; a light source for light excitation; a irradiation optical system; a fluorescence collecting system; a dividing section which divides collected light at ratios substantially different for each wavelength in a specified wavelength range; an imaging optical system which forms an image of each divided light flux on a detector; the detector including a plurality of pixels for detecting the formed image of each divided light flux; and a data processing section which determines a fluorescent material type on a basis of an intensity ratio of the detected light flux.
