چکیده
The method of Raman spectroscopy (RS) is widely used for timely metrological support technological lines the industrial sector in chemical, medical and pharmaceutical, food, as well criminalistics forensic examinations. wide application requires use specific tools, namely, measures calibrating spectrometers microscopes according to spectrum shape (i. e. relative spectral sensitivity). purpose research was develop prototype designed calibrate on a scale intensities provided with traceability SI base units. Prototype were made from inorganic glasses based an oxide matrix, each activated metal ions selected excite broad fluorescence line radiation at given wavelength: 532 nm (manganese ions), 633 (bismuth ions) 785 (chromium ions). Metrological characteristics established measures, where certified characteristic intensity reproduced radiation. maximum expanded measurement uncertainty coverage factor k = 2 determined, which 9.4 %, 5.2 % 2.8 reproduce when excited wavelengths nm, respectively. Certification performed laser confocal microscope Confotec NR500, part GET 196-2015 standard, allows establishing through 8 6-2017 microscope, providing units “(light) energy flux” value. Thus, it possible find correction function determining spectra traceable State Primary Standard calibrated devices using measures. practical significance results makes expand possibility monitoring stability calibration spectrometers, intensities.
