Function Of Chopper In Spectroscopy at Tommy Graves blog

Function Of Chopper In Spectroscopy. A chopper which is placed between the radiation source and the flame is meant to break the continuous light. 3.2.4 chopper a chopper is a device that splits a single beam of radiant light into two directions. In the context of spectroscopy. Instead of directly measuring the optical power with some photodetector , one registers an oscillating power of a chopped beam. the purpose of the chopper is to provide a means for discriminating against the emission of light from the flame, which will otherwise contribute to the total amount of light that reaches the detector. As shown in figure \(\pageindex{3}\), when the chopper is closed, the only light reaching the detector is from the flame; a chopper by itself does not eliminate drift, a chopper and a highpass (or bandpass) filter eliminate drift.
