In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. This could be a mass-to-charge ratio spectrum in the case of a mass spectrometer, the variation of nuclear resonant frequencies in an NMR spectrometer or the change in the absorption and emission of light with wavelength in an optical spectrometer.

The most ubiquitous type of spectrometer used for research are optical spectrometers; and when someone simply says ‘spectrometer’, without an additional qualifier, they are usually referring to an optical spectrometer and this diverse family of spectroscopic instruments is the focus of this article. The core spectral scanner is an earth detection instrument used in the field of earth science and mine engineering technology, which was launched on January 1, 2016 It breaks the single function of traditional core image scanning, and increases the spectral acquisition of altered minerals. Through data inversion, rapid automatic core cataloging and altered mineral mapping are realized, providing important technical means for core digitization and establishment of core database. Through rapid analysis of core mineral structure, the instrument can obtain a large amount of mineral digital information, rapid analysis of low-temperature alteration minerals such as monomeric minerals, hydroxy-containing silicate minerals, sulfate minerals and carbonate minerals in stratified silicates, for geological exploration, borehole cataloging, alteration mineral mapping, prospecting target area selection, mineralization indication, mineralization potential evaluation, and mineral exploration. Mineral geochemistry and crystallography, grade control in mining, clay content monitoring in waste materials, and identification of auxiliary remote sensing pictures provide advanced measurement means to solve the problem of a large amount of money and resource waste caused by the abandonment of a large number of core, which has a high practical value in practical work. Provide convenience for geological research materials.
