InSpectr L405 portable luminescence express analyser

Express luminescence portable analyser "Inspectr "L405 is a luminescence analyser that combines high resolution and wide spectral range in a compact body. Luminescence spectroscopy is actively used in gemology to verify the authenticity of precious and semi-precious stones, as well as to check whether jewellery has been pre-treated to increase its selling value. For example, a combination of Raman and luminescence spectroscopy is used to detect if gemstones have been pre-treated with temperature and high pressure. For express tests of jewellery authenticity our company has developed an express Raman portable analyzer "Inspectr" L405. As a source of excitation used violet laser with a wavelength of 405 nm, which allows measurements in the visible and near-infrared range (455-760 nm) with spectral resolution (0.45-0.6 nm)..
