Abstract:
1. A method of illuminating a plurality of reaction regions, the method comprising: providing a plurality of light emitting diode sources distributed throughout a two-dimensional array; providing a plurality of reaction regions comprising a two-dimensional array of spaced-apart reaction regions; providing an array detector; generating a plurality of excitation beams with the plurality of light emitting diode sources such that plurality of light emitting diode sources illuminate every reaction region of the two-dimensional array of spaced-apart reaction regions; directing the excitation beams through a plurality of lenses and into the two-dimensional array of spaced-apart reaction regions; generating emission beams from the two-dimensional array of spaced-apart regions; and directing the emission beams to the plurality of lenses and a beam splitter and onto the array detector.
