Fiber optic light sources for gem identification
Cold light sources, also known as fiber optic lights, provide a focused and stable illumination essential for gemstone examination. These light sources operate with high brightness and low power consumption, ensuring a continuous spectrum from 400nm to 700nm. Unlike conventional lighting, fiber optic light reduces heat output, preventing thermal damage to sensitive gemstones during analysis.
Application
- Works with gem spectroscopes to reveal absorption spectra, helping identify a gemstone’s composition and authenticity.
- Used with a Chelsea Filter to check whether blue or green gemstones exhibit a red reaction, distinguishing natural from synthetic or treated stones.
