Description
The Grating Spectroscope is an indispensable tool for the modern gemologist, especially when working with infrared or near-infrared spectra. This portable visible light spectroscope shows the absorption lines of the elements responsible for creating the color of the stone. For example, it helps distinguish ruby (chromium) from red or pink sapphire (iron).
Main advantages:
- Quality spectra: The device produces clear and sharp spectra even when using low-intensity light.
- Compact dimensions: A "lipstick" sized spectroscope with a fixed focus and slit is ideal for fast and accurate investigations.
- Versatile use: In addition to gems, you can also examine liquids or flames colored with metallic salts.
Use: The spectroscope requires quality training and a suitable light source for proper operation. Colorless stones do not show an absorption spectrum. Sunlight shows a typical absorption spectrum with Fraunhofer lines, while fluorescent lights show an emission spectrum.
