The Gem-A Prism Spectroscope is used to test coloured gem materials by observing their absorption spectra. Light is naturally dispersed through a series of prisms, resulting in a wider blue region in this spectroscope, which allows for easy reading of spectra of stones with absorption lines within this range. The adjustable focus sharpens different parts of the spectrum to suit the user's eyesight. Both easy to use and portable.
We are open from Monday to Friday.
