Abstract

Astronomical spectroscopy is the main tool to investigate the physical properties of celestial sources and celestial environments, in particular the composition, temperature, and density. The most part of astronomical spectrographs in the optical domain is based on dispersing elements, such as the diffraction gratings. This chapter presents the discussion of the different dispersers and how they can be used in spectrographs. The spectral resolution is discussed for different situations. The spectroscopy with CCDs is presented.
