Abstract:
A fluorescence spectrometer which comprises:a laser; at least one beam splitter positioned to receive a light beam from the laser and to divide said beam into a plurality of separate, first light beam portions; dichroic mirrors positioned to separately receive said first light beam portions and to reflect said beam portions at an angle to said first light beam portions; a plurality of transparent chambers for holding samples; objective lens systems respectively positioned in the path of said reflected beam portions to respectively focus each reflected beam portion to a point within one of said separate, transparent chambers; lenses respectively positioned to receive fluorescence from a sample for testing within said transparent chambers and to respectively focus said fluorescence at pinholes in opaque partitions, said lenses being positioned to receive said fluorescence which passes back through said objective lens system and said dichroic mirror; light detectors each respectively positioned adjacent to one of said partitions with one said partitions respectively positioned between each of said lenses and said light detectors, to permit each light detector to sense fluorescence through said pinhole; and electronics to receive and process signals from each light detector.
