Development of the USB-Spectrophotometer for Studying the Spectra of Light Absorption by Substance.

In modern science and technology, various methods are used to determine the chemical composition and physical properties of substances. Among them, spectral analysis is one of the most important methods. To obtain and study the spectrum of a substance emission and its absorption of visible radiation, a device that has interface with a personal computer has been developed. The device is unattached and can be used in field experiments, for example, in Arctic expeditions. [ABSTRACT FROM AUTHOR]
