Patent ID: 7928408

Claim:
A multi-channel fluorescence sample analyzer for irradiating light onto a plurality of sample channels and detecting fluorescence radiated from samples to analyze the samples, comprising: a light source; an integrator which increases a uniformity of the light irradiated from the light source; a sample holder having a plurality of sample channels on which the samples are mounted, wherein the samples are excited by the light emitted from the integrator, and wherein the sample holder is uniformly exposed to the light emitted from the integrator such that each portion of the sample holder receives substantially a same amount of light; a beam splitter between the integrator and the sample holder for dividing light incident thereto in a predetermined ratio; and a light detecting unit for simultaneously detecting fluorescence from the samples through the beam splitter, wherein fluorescence images of the samples in the plurality of sample channels are detected as florescence intensities in the light detecting unit, and the sample holder, the beam splitter and the light detection unit are arranged to transmit light from the plurality of sample channels to the light detection unit along substantially parallel optical paths, wherein the light detecting unit has optical fiber bundles corresponding to the sample channels, and photodiodes which face the optical fiber bundles respectively such that the fluorescence images emitted from the sample channels through the optical fiber bundles are detected.
