The Gem-A Diffraction Grating Spectroscope is an invaluable instrument, used to test coloured gem materials by observing their absorption spectra, producing a uniform, linear spectrum. 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.
