An instrument that spreads out the light gathered by a telescope so that it can be analyzed to determine many different properties of celestial objects These properties include the chemical composition and abundance of different elements, temperature, radial velocity, rotational velocity, and magnetic fields
An instrument for separating and recording the spectral components of light Contemporary instruments use electronic cameras to record the spectra
An instrument that spreads light or other electromagnetic radiation into it's component wavelengths (spectrum), recording the results photographically or electronically
A device that separates light by wavelength (color) in order to produce a spectrum that allows for the identification of elements within the light source We have a spectrograph attachment for the CCD camera from SBIG
basically the same as the spectroscope except that the eyepiece is replaced by a photographic plate for recording the spectrum
A spectroscope provided with a photographic camera or other device for recording the spectrum
device that separates charged particles into groups according to their mass (used to determine frequency of isotopes or to discover the ingredients of an unknown substance)
An instrument used to determine the masses of atoms or molecules, in which a beam of charged particles is passed through an electromagnetic field that separates particles of different masses. The resulting distribution or spectrum of masses is recorded on a photographic plate.mass spectrography n
