Abstract:
A fluorescence detection apparatus comprising:a sample holder for fixing and holding a plurality of vessels on a circular arc; a driving unit; a partition plate for rotating integrally by being joined to said driving unit; an excitation light source coupled to said partition plate; an excitation light optical unit; a fluorescence optical unit being fixed on said partition plate for rotation integrally; and at least one photosensor for detecting a fluorescence signal from each of samples in the sample vessels, wherein said partition plate comprises a passing portion for allowing the fluorescence signal through passing from the sample vessels, wherein said photosensor is mechanically discontinued from said drive unit and fixedly placed, wherein said excitation light optical unit is placed so as to selectively excite one of the sample vessels in order, corresponding to the rotation of the partition plate, wherein said fluorescence optical unit includes a light guide for communicating the fluorescence signal from the sample vessel to said photosensor, and an incidence end of said light guide is placed facing said passing portion and an emission end of said light guide is placed on a center axis of the rotation facing said photosensor.
