spectrometer


spectrometer

any instrument for producing a spectrum, esp one in which wavelength, energy, intensity, etc., can be measured

spectrometer

(spek-trom -ĕ-ter) 1. an instrument, such as a spectrograph, in which the spectrum of a source of radiation is produced, especially one in which the spectrum is recorded by electronic means so that wavelength, intensity, etc., can be measured. Spectrometers covering various wavelength ranges are used in ground-based and satellite and spaceprobe measurements. 2. an instrument for determining the distribution of energies in a beam of particles.

Spectrometer

 

In the broad sense, a spectrometer is an instrument for measuring the distribution of some physical quantity I as a function of a parameter x. For example, the function f(x) may define the distribution of electrons with respect to velocity (beta-ray spectrometer), the distribution of atoms with respect to mass (mass spectrometer), the distribution of gamma quanta with respect to energy (gamma-ray spectrometer), or the distribution of luminous intensity with respect to wavelength λ (optical spectrometer).

In the narrow sense, a spectrometer is a spectroscopic instrument for measuring optical spectra f (λ) by means of photoelectric radiation detectors.

spectrometer

[spek′träm·əd·ər] (spectroscopy) A spectroscope that is provided with a calibrated scale either for measurement of wavelength or for measurement of refractive indices of transparent prism materials. A spectroscope equipped with a photoelectric photometer to measure radiant intensities at various wavelengths.

spectrometer 

An instrument for making measurements of the angle of a prism and the index of refraction. It consists of a collimator, an astronomical telescope, a table for carrying a prism and a graduated circle.
