Editing Monochromator (section)

*[[Atomic absorption spectroscopy|Atomic absorption]] spectrometers use light from [[hollow cathode lamp]]s that emit light generated by atoms of a specific element, for instance iron or lead or calcium. The available colors are fixed, but are very monochromatic and are excellent for measuring the concentration of specific elements in a sample. These instruments behave as if they contained a very high quality monochromator, but their use is limited to analyzing the elements they are equipped for.
* A major IR measurement technique, [[Fourier transform spectroscopy|Fourier transform]] IR, or FTIR, does not use a monochromator. Instead, the measurement is performed in the time domain, using the [[optical autocorrelation|field autocorrelation]] technique.
*[[Polychromator]]
*[[Ultrafast monochromator]] – a monochromator that compensates for path length delays that would stretch [[ultrashort pulse]]s
*[[Wien filter]] – a technique for producing "monochromatic" electron beams, where all the electrons have nearly the same energy
