A spectroscope is used to reveal a colored spectrum of a gem by passing artificial light through it. This spectrum is a unique pattern of rainbow-like colors and dark lines or bands for each species of gemstone, so can be used as an identifying criteria.
This large OPL Diffraction Spectroscope comes with a larger eyepiece to allow easier observation of spectrums. The spectroscope is supplied with a Rotating Stand so as to observe spectra easily in loose gemstones, and to provide hands free operation.
This item is best used with a fibre optic light.
Instructions for use can be found in “A Students’ Guide to Spectroscopy” by C. Winter. This can be found in our Book section.
