spectrometer
(device to measure light by wavelength across its spectrum)
The term spectrometer is for a device that measures a spectrum,
e.g., the intensity of light at different wavelengths,
a practice called spectrometry.
As such, a spectroscope or spectrograph can
be termed a spectrometer.
Those two terms originally distinguished between a device that
you look through (spectroscope) and one that recorded the spectrum
on film (spectrograph), but
modern advanced instruments virtually always focus the spectrum on
a CCD or similar sensor, allowing the spectral data to be
transmitted, recorded and analyzed electronically, and any of the
three terms may be used.
The terms may be used for analyzers
of any part of the electromagnetic spectrum, but when used for other
than visible light, that is usually mentioned, e.g., the phrase
"X-ray spectrometer".
Spectrometers are used as lab instruments and telescope instruments.
The term mass spectrometer is used for a different kind of
device that does not concern light or other EMR: one that measures
the relative number of particles entering it according to each
individual particle's mass.
Space probes often include mass spectrometers to analyze material
collected, such as dust. Information about the masses
provide clues to its makeup.
