Abstract:
A device for measuring fluorescent light emitted by sample-reagent mixtures contained in a plurality of reaction vessels, said device comprising:(a) an array of photodiodes built on a chip, wherein each of the photodiodes of the array is capable of receiving fluorescent light emitted by a sample-reagent mixture contained in one of said plurality of reaction vessels and providing an output signal representative of the intensity of said fluorescent light; and(b) an integrated electronic circuit connected to said array of photodiodes for processing output signals provided by said photodiodes of said array, said integrated electronic circuit being mounted on said chip on which said array of photodiodes is built and said integrated electronic circuit comprising first electronic circuit means for amplifying and integrating the output signals of said photodiodes and for providing output signals obtained by sequential reading of the integrated output signals, said sequential reading of the integrated output signals being a reading in non-destructive mode;wherein output of each of said photodiodes of said array of photodiodes is directly connected to a corresponding input of said integrated electronic circuit.
