Claim:
1. A system for detecting two or more different optical emission signals emitted from each of a plurality of reaction receptacles, wherein the reaction receptacles are disposed in a fixed arrangement with respect to each other, said system comprising: (A) a plurality of optical sensors, each of said optical sensors being configured to detect one of the two or more optical emission signals and being associated with one of the reaction receptacles so that each reaction receptacle has associated therewith one optical sensor for each optical emission signal to be detected, whereby said optical sensors associated with each of the plurality of reaction receptacles are arranged in a configuration that enables each optical sensor to detect the associated optical emission signal emitted from the associated reaction receptacle; (B) a transport mechanism constructed and arranged to effect relative movement between the plurality of reaction receptacles and the optical sensors to sequentially place each reaction receptacle into a signal-detecting position with respect to one of its associated optical sensors, wherein (C) circuitry configured to discard any portion of an optical signal detected by an optical sensor having a frequency that is inconsistent with the excitation frequency of the associated excitation signal.
