Any of various instruments used to analyze a sample by separating its components into a spectrum.
spec′tro·scop′ic (-skŏp′ĭk), spec′tro·scop′i·cal (-ĭ-kəl) adj.
(General Physics) any of a number of instruments for dispersing electromagnetic radiation and thus forming or recording a spectrum. See also spectrometer
[C19: from spectro- + -scope; from French, or on the model of German Spektroskop]
spectroscopic, ˌspectroˈscopical adj
an optical device consisting essentially of a collimating lens and a prism, for observing a spectrum of light or radiation.
spec`tro•scop′ic (-ˈskɒp ɪk) spec`tro•scop′i•cal, adj.
Any of various instruments used to measure the wavelengths and intensity of radiation by splitting the radiation up into a spectrum. In a light spectroscope, light enters a narrow slit, is focused into a thin beam of parallel rays by a lens, and passes through a prism that separates it into a spectrum. Other types of spectroscopes, such as the mass spectroscope, use magnetic fields to separate the incoming radiation.
a device for producing and observing a spectrum of light or other radiation. — spectroscopy, n.See also: Instruments
