    Abstract: An optoelectronic device is provided which permits rapid sequential measurement of the optical density of multiple samples. The device employs a plurality of light-emitting diodes (LEDs) as light sources and a plurality of photodiodes as light detectors. In a preferred embodiment, arrays of LEDs paired with photodiodes are adapted to measure the optical density of samples contained in multiwell plastic plates (microplates) conventionally used for immunoassays.

    Abstract: The invention relates to photometric apparatus and method for determining a characteristic of individual ones of a plurality of samples contained within a plurality of sample chambers. The photometric apparatus includes an enclosure; a substantially uniform source of radiation coupled to the enclosure such that a plurality of sample chambers, disposed within the enclosure, are simultaneously illuminated by the uniform source; and apparatus for detecting an amount of radiation which is transmitted through individual ones of the sample chambers, the detecting apparatus having an output signal having a magnitude which is a function of the amount of radiation which is transmitted through an individual one of the sample chambers. The substantially uniform source of radiation may include at least one source of radiation having an output comprising wavelengths within a first range of wavelengths and an optically integrating sphere having a radiation input port coupled to the output of the source of radiation and a radiation output port coupled to the enclosure. The photometric apparatus may further include radiation directing devices interposed between the radiation output port and the plurality of sample chambers for simultaneously directing radiation emanating from the output port into each of the sample chambers. The directed radiation may be either focussed or collimated.
