Spectroscopes are used to generate and analyse colour spectra of coloured stones. These absorption spectra are almost like an individual fingerprint and many stones can be determined with this method or stones of the same colour can be separated from one another quickly and reliably. We offer high quality portable hand-held spectroscopes in different designs. Depending on the model, the specifications include, for example, an additional wavelength scale 400-750 nm, the linear dispersion of 60 mm, an adjustable slit and an angular dispersion of C-F7 °. We also offer a device set with a hand-held spectroscope including a spectroscope stand and cold light source.
