| spectrometer |
An instrument which separates radiation into energy bands (or, in a mass spectrometer, particles into mass groups) and indicates the relative intensities in each band or group.

Instrument used to produce detailed spectra of stars. Usually, a spectrograph records a spectrum on a photographic plate, or more recently, in electronic form on a computer.

| spectroscopy |
An analytical technique devoted to the identification of the elements and the elucidation of atomic and molecular structure by measurement of the radiant energy absorbed or emitted by a substance in any of the wavelengths of the electromagnetic spectrum in response to excitation by an external energy source.

| spectrum |
or visible spectrum Band of electromagnetic radiation ranging from wavelengths of approximately 400 to approximately 700 nanometers, corresponding to the sensitivity of the human eye. Sensitivity does not drop to zero at the standard endpoints of the visible spectrum, but is so low that light outside these limits rarely has a significant effect on visual response. Many non-human animals respond significantly to light outside this range, especially to light of shorter wavelengths.

| spectral reflectance |
(of a surface) At each wavelength in the visible spectrum, the proportion of incident light the surface reflects at that wavelength.
