Wiktionary
spectrometer

n. (context analytical chemistry English) An optical instrument for measuring the absorption of light by chemical substances; typically it will plot a graph of absorption versus wavelength or frequency, and the patterns produced are used to identify the substances present, and their internal structure.

spectrometer

n. spectroscope for obtaining a mass spectrum by deflecting ions into a thin slit and measuring the ion current with an electrometer [syn: mass spectrometer]

Wikipedia
Spectrometer

In physics, a spectrometer is an apparatus to measure a spectrum. Generally, a spectrum is a graph that shows intensity as a function of wavelength, of frequency, of energy, of momentum, or of mass.
