FLUOROMETER, RODAMINE SEA POINT
Description
FLUOROMETER, RODAMINE SEA POINT The SRF uses modulated green LED lamps and green interference filters to excite Rhodamine WT. The fluorescent light emitted by the Rhodamine WT passes through an orange emission filter and is detected by a silicon photodiode. The low level signal is thenprocessed using synchronous demodulation circuitry which generates an output voltage proportional to Rhodamine WT concentration. |
