More Information
Summary:A method for detecting two or more different optical emission signals emitted from each of a plurality of reaction receptacles, said method comprising, for each optical emission signal to be detected, the steps of: (a) directing an optical excitation signal at each reaction receptacle, the optical excitation signal having a known wavelength that excites an associated optical emission signal having a known emission wavelength, wherein the optical excitation signal has a known excitation frequency; (b) detecting an optical signal which includes any optical emission signal emitted by the contents of each receptacle; and (c) discarding any portion of the detected optical signal having a frequency that is inconsistent with the known excitation frequency to determine the portion of the detected optical signal that corresponds to the associated optical emission signal.
