Focusing Prism Spectroscope

Gemologists use a focusing prism spectroscope to analyse the spectrum of gemstones. This instrument disperses light passing through a stone into its spectral colours and enabling the observation of specific wavelengths absorbed by the stone.

Main Advantage: The focusing prism spectroscope offers precise adjustment capabilities, allowing users to focus on different parts of the spectrum. It has a wavelength range of 400-700nm that covers the entire visible spectrum for analysis. It is portable and user-friendly due to its compact design.

The prism spectroscope is an invaluable tool used to distinguish natural-coloured diamonds from irradiated ones, as well as for distinguishing between natural and synthetic stones through selective absorption analysis of certain wavelengths.
