Great price Exclusive Handheld Prism Spectroscope for Gemstone Identification, High Resolution, Adjustable Focus and Slit, Silver-like Metal, Buy Now!

A spectroscope is an optical instrument used to identify gemstones by analyzing how the stone absorbs light. Different elements and impurities in the stone absorb specific wavelengths, creating a unique "fingerprint" in the form of dark lines or bands in a colored spectrum.

Prism Spectroscope

Technology: Uses glass prisms to refract the light. Since different wavelengths are refracted differently (dispersion), the light is spread out into a visible spectrum.

Properties: The red region of the spectrum is greatly stretched, making it easier to distinguish and measure specific absorption lines in the red part (e.g. in ruby). However, the blue and violet region is greatly compressed.
