Spectroscope device set

Device set: Handheld spectroscope with spectroscope stand and cold light source

Accurate gemstone analysis by means of light spectrum analysis. A gemstone spectroscope breaks up the light being transmitted from a gemstone into its spectral colours. This allows the various wavelengths being absorbed by the gemstone to be viewed. This, in turn, translates into the elements which are contained in the gemstone that are creating the absorption, thereby determining the quality and type of stone. Fraunhofer lines and bands are also deployed for analysis. Therefore, the spectroscope is an important tool in gemmology examinations, assessments and appraisals.

The gem spectroscope SET has a Amici prism (5 prism) that delivers a sharp spectrum, so that faint lines are easy to view. It has a built-in adapter for scale illumination, and an adapter plate for light source and an integral polariser. The Set includes also the light guide and the cold light source. Complete with automatic voltage switching, covering 110-230V range.
