Description
The spectroscope is an important tool of the modern gemologist. This concerns the infrared or near infrared spectroscopes. A handheld spectroscope for visible light shows the absorption lines of the elements involved in producing its color. It helps to separate ruby (chrome) against red or pink sapphire (iron) to name only one example. This tool requires a good training and an appropriate light source. Colorless stones show no absorption spectrum. The sunlight shows a typical absorption spectrum, the Fraunhofersche lines. Fluorescence lamps show an emission spectrum. Fordemonstration you may examinate besides gemstones also liquids or flames colored by metal-salts.
The model GI-7205 is a prism type. It is composed of three optical grade glass prisms in optical contact with each other. It is equipped with adjust screw, the window can be focused.Ideal for demonstrations and quick laboratory observations, our easy-to-use, palm-sized instrument provides fast, accurate spectra from any visible light source. Features a precision lens and 3-element amici prism system housed in a stainless steel tube. Adjustable slip-type focus and optical slit. As slit opening diminishes, contrast decreases while resolution increases. Fits bar-type, holders for optical bench.
