In spectrum …or maps spectra is a spectrograph. Spectra may be classified according to the nature of their origin—i.e., emission or absorption. An emission spectrum consists of all the radiations emitted by atoms or molecules, whereas in an absorption spectrum portions of a continuous spectrum (light containing all wavelengths) are missing because…
STIS is a versatile instrument that combines a camera with a spectrograph to analyse the light of celestial objects. It can switch between long slit and echelle spectroscopy modes, and has a coronograph to block light from bright objects.
Learn about spectrographs, devices that disperse light into its component wavelengths, from various fields of physics and astronomy. Find definitions, equations, diagrams, and examples of spectrographs and their applications.
Two-dimensional spectrographs used for Raman spectroscopy. (A) combination of a filter spectrograph and a diffraction spectrograph. F1, F2, and F3 are dichroic beam splitters; G1 is a diffraction grating; L1 is a camera lens; FP is the exit focal plane. (B) Echelle spectrograph for Raman spectrometry.
Spectrograph. A spectrograph is an instrument that breaks up a wave into a frequency spectrum. These could be sound, light or radio waves. For example the frequency spectrum of light is the brightness (intensity) and the amount of each colour. There are several kinds of machines called spectrographs, used to look at different waves.

Bloomsbury Publishing USA, Aug 29, 2013 - Social Science - 584 pages. The Spectralities Reader is the first volume to collect the rich scholarship produced in the wake of the “spectral turn” of the early 1990s, which saw ghosts and haunting conjured as compelling analytical and methodological tools across the humanities and social sciences.
