Fiber optic light sources for gem identification
Cold Light Source / Fiber Optic Light

Cold Light Source / Fiber Optic Light

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.
