Miniaturized fluorescence analysis system

摘要

According to embodiments of the present invention, a fluorescence analysis system includes a light emitting diode (LED) array to excite a fluorophor sample for analysis. The system includes an LED array driver that pulses the LEDs in the array with currents in excess of maximum rated current at low duty cycles to reduce LED degradation over time. An LED selection optimization process and software select the LEDs to be included in the array from among various colors and currents to be applied. The LED selection optimization process and software take filters and attenuation into consideration.
