n. an optical device consisting essentially of a collimating lens and a prism, for observing a spectrum of light or radiation. [1860–65] spec`tro•scop′ic (-ˈskɒp ɪk) spec`tro•scop′i•cal, adj. spec`tro•scop′i•cal•ly, adv. spec·tro·scope (spĕk′trə-skōp′) 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.spectroscopea device for producing and observing a spectrum of light or other radiation. — spectroscopy, n.See also: InstrumentsThesaurus| Noun | 1. |  spectroscope - an optical instrument for spectrographic analysisprism spectroscopecollimator - optical device consisting of a tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beammass spectrometer, spectrometer - spectroscope for obtaining a mass spectrum by deflecting ions into a thin slit and measuring the ion current with an electrometeroptical instrument - an instrument designed to aid visionoptical prism, prism - optical device having a triangular shape and made of glass or quartz; used to deviate a beam or invert an imagespectrograph - a spectroscope by which spectra can be photographed |

spectroscope, optical instrument for producing spectral lines and measuring their wavelengths and intensities, used in spectral analysis (see spectrumspectrum,
arrangement or display of light or other form of radiation separated according to wavelength, frequency, energy, or some other property. Beams of charged particles can be separated into a spectrum according to mass in a mass spectrometer (see mass spectrograph).

In the original spectroscope design in the early 19th cent., light entered a slit and a collimating lens transformed the light into a thin beam of parallel rays. A prism then separated the beam into its spectrum. The observer then viewed the spectrum through a tube with a scale that was transposed up the spectrum image, enabling its direct measurement. With the development of photographic film, the more accurate spectrograph was developed. It was based on the same principle as the spectroscope, but it had a camera in place of the telescope. In recent years the electronic circuits built around the photomultiplier tube have replaced the camera, allowing real-time spectrographic analysis of far greater accuracy. Such spectrum analysis, or spectroscopy, has become an important scientific tool for analyzing the composition of unknown material. It has found applications in fields as disparate as astronomy and forensic chemistry.spectroscope[′spek·trə‚skōp] (spectroscopy) An optical instrument consisting of a slit, collimator lens, prism or grating, and a telescope or objective lens which produces a spectrum for visual observation. spectroscope any of a number of instruments for dispersing electromagnetic radiation and thus forming or recording a spectrum spectroscope
spectroscope [spek´trah-skōp] an instrument for developing and analyzing the spectrum of a substance. adj., adj spectroscop´ic.spec·tro·scope (spek'trō-skōp), An instrument for resolving light from any luminous body into its spectrum, and for the analysis of the spectrum so formed. It consists of a prism that refracts the light or a grating for diffraction of the light, an arrangement for rendering the rays parallel, and a telescope that magnifies the spectrum.
