单词 spectroscope
释义
spectroscope

Physics
  • An optical instrument that produces a spectrum for visual observation. The first such instrument was made by Joseph von Fraunhofer; in its simplest form it consists of a hollow tube with a slit at one end by which the light enters and a collimating lens at the other end to produce a parallel beam, a prism to disperse the light, and a telescope for viewing the spectrum. In the spectrograph, the spectroscope is provided with a camera to record the spectrum. For a broad range of spectroscopic work, from the ultraviolet to the infrared, a diffraction grating is used instead of a prism. See also spectrometer.

    spectroscope

    Spectroscope.


Astronomy
  • An instrument that produces a spectrum for visual observation. Spectroscopes are now used mainly for educational and recreational purposes; research instruments employ CCD detectors to record the spectrum, and hence are spectrographs.


Chemistry
  • An optical instrument that produces a spectrum for visual observation. The first such instrument was made by Robert Bunsen; in its simplest form it consists of a hollow tube with a slit at one end by which the light enters and a collimating lens at the other end to produce a parallel beam, a prism to disperse the light, and a telescope for viewing the spectrum. In the spectrograph, the spectroscope is provided with a camera to record the spectrum.

    For a broad range of spectroscopic work, from the ultraviolet to the infrared, a diffraction grating is used instead of a prism. See also spectrometer.


Geology and Earth Sciences
  • An instrument used in spectroscopy, whose main features are a slit and collimator, prism, telescope, and counter. A parallel beam of radiation is passed through the prism, so dispersing different wavelengths through different angles of deviation, which can be measured.
