Testing the device using a spectrometer or spectrograph for the dispersion of visible light (includes electromagnetic, electron, and acoustic spectroscopy).

(Device Spectroscopy Evaluation Method, Food and Drug Administration)

A spectrograph is a diagnostic tool that divides light from an object into its many individual wavelengths to determine its speed, temperature, and other characteristics at a very high precision.

(Hubble Uncovers Black Hole Disk that Shouldn't Exist, NASA)

The line moving across the middle of the movie is the entrance slit for IRIS's spectrograph, an instrument that can split light into its many wavelengths – a technique that ultimately allows scientists to measure temperature, velocity and density of the solar material behind the slit.

(Observing a Gigantic Eruption of Solar Material, NASA)

Examining data collected by the ultraviolet spectrograph and energetic-particle detector instruments aboard the Jupiter-orbiting Juno spacecraft, a team led by Barry Mauk of the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, observed signatures of powerful electric potentials, aligned with Jupiter's magnetic field, that accelerate electrons toward the Jovian atmosphere at energies up to 400,000 electron volts.
