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. The high-quality overall equipment makes the spectroscope an important tool for evaluation and assessment in gemmological investigations. Well suited for identifying rubies, spinels, garnet, alexandrite or red tourmaline.
