Abstract
A fluorescence detecting apparatus which allows highly precise measurement of fluorescence even with minute sample amounts, which has a strong responsiveness to temperature variations, which allows simultaneous measurement of a plurality of samples, and wherein the light source and the container holder, and the container holder and the fluorescence detector, are each optically connected by optical fibers; and the optical fibers are connected to the container holder in such a manner that the sample in the container is excited for fluorescence from below the sample container held by the container holder, and that they may receive the fluorescent light which is emitted by the sample from below the sample container.

A fluorescence detecting apparatus comprising:
- a sealed sample container for holding a sample;
- a container holder for holding the sample container and means for varying the temperature of the sample in the sample container;
- a fluorescence detector for measuring the fluorescence from the sample;
- and
- a light source for emitting an exciting light to excite the sample for fluorescence;
- wherein said light source and said container holder, and said container holder and said fluorescence detector, are each optically connected by optical fibers;
- said optical fibers being connected to said container holder and arranged such that the sample in said container is excited for fluorescence from below said sample container held by said container holder, and said optical fibers receive fluorescent light emitted by the sample from below said sample container.
