| 1. A fluorescence detector comprising:
a flow cell provided on a flow passage for flowing a sample;
a sample temperature control block for keeping the flow cell and the flow passage located on the sample inlet side of the
flow cell at a constant temperature;
an excitation optical system for guiding excitation light to the flow cell;
a fluorescence optical system having a photodetector and used for guiding fluorescence emitted from a sample flowing through
the flow cell to the photodetector for detecting the fluorescence;
a photodetector temperature control block for keeping the photodetector at a constant temperature; and
a temperature control unit having a simultaneous temperature control block,
wherein the simultaneous temperature control block is (a) united with both the sample temperature control block and the photodetector
temperature control block and (b) is in contact with a temperature control system which heats and/or cools the simultaneous
temperature control block.
