Hand-held spectroscope HS1504

Accurate gemstone analysis by means of light spectrum analysis

The HS1504 gem spectroscope has a Amici prism (5 prism) that delivers a sharp spectrum. A gemstone spectroscope provides maximum clear measurement results as a result of its uncomplicated measurement methodology. Our prism spectroscope gives a far brighter spectrum, which makes faint lines easier to see. These instruments will usually have a focus slide control as well as a light slit control, allowing for adjustments in the amount of light entering the unit. Therefore, the spectroscope is an important tool in gemmology examinations, assessments and appraisals. Well suited for identifying rubies, spinels, garnet, alexandrite or red tourmaline.
