Abstract : This patent discloses a stable, inexpensive and easily constructed photometer consisting of a commercial integrated photodetection assembly, complementary solid-state operational amplifiers and a solid-state power supply for use in the detection and quantification of low level light emissions from bioluminescence organisms and for the detection of the absence of bioluminescence. Means are provided for controlling the sensitivity of the system as well as providing for direct readout or integration of the detected signals where they are intermittent. Keywords: Dinoflagellates bioluminescence. Patents. (EDC)
