WebThe emission is collected at the perpendicular to the emitted light. The emission is also either passed through a filter or a monochromator before being detected by a photomultiplier tube, photodiode, or charge-coupled device detector. The signal can either be processed as digital or analog output. http://alpha.chem.umb.edu/chemistry/ch117/117%20labs/Spectra
