GEM Gemstone Diffraction Spectroscope, Spectrascope
Item description: Diffraction Spectroscope for Testing COLORED Gemstones
An easy to use, the clear sharp focus of the spectrum will quickly enable you to analyze the readings for your gemstones.Light enters through a narrow slit and is then diffracted by a thin film of diffraction grating material. This produces a linear spectrum image with a generally larger view of the red part than a prism spectroscope.This spectroscope does not have a built-in scale. The Spectroscope measures light absorption in a gemstone.
Simply put, if a certain light spectrum is missing, you then have a clue as to which sort of stone you may have. This instrument is handy for all sorts of stones, real or synthetic!
