Gemology spectroscope
WebSpectroscopy in Gemology. The use of spectroscopy in the study of gems and minerals began not long after Isaac Newton first experimented with the separation of the sun’s light into its component colours when split by a prism. By the mid-1800s, scientists were mapping the solar spectrum and beginning to identify absorption spectra for many ... WebThe spectroscope uses the principle of diffraction. It breaks down the light into rainbow colors, like the diagram below. Scattering of light through a prism. Source Wikipedia. The …

WebIntroduction to Infrared Spectroscopy (FTIR) in Gemology. Most gemologists are familiar with the direct vision spectroscope. This instrument uses a series of prisms or a diffraction grating to separate white light into its spectral components. If white light is passed through a gem, it will reveal any areas of absorption or emission. Spectroscopes are often used in astronomy and some branches of chemistry. Early spectroscopes were simply prisms with graduations marking wavelengths of light. Modern spectroscopes generally use a diffraction grating, a movable slit, and some kind of photodetector, all automated and controlled by a computer. Recent advances have seen increasing reliance of computational algorithms i…
