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

[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

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.

The specially prepared, certified specimens of Cr18Ni10Ti high-alloy austenitic steel and AK12MMgN (AL30) high strength cast piston aluminium alloy were used for testing the analytical possibilities of the SPECTRO xSORT spectrometer. The results of the tests are presented in Table 1 in which the measured values of the alloying chemical elements and impurities in the alloys were obtained at the simultaneous determination and averaging five parallel experiments with the calculation of the RMS error of measurements.
