Jade detection

LEDs are used in jade detection in the following ways: Illumination: LEDs provide consistent and controlled light to help inspect the surface, color, and texture of the jade. Different wavelengths and intensities of LED light can reveal hidden flaws, inclusions, or patterns within the jade. Spectroscopy: Specialized LED light sources in combination with spectrometers can be used to analyze the optical properties of the jade. This helps determine its authenticity, origin, and quality by measuring how the jade interacts with the LED-generated light in terms of absorption, reflection, and transmission. Backlighting: LEDs placed behind the jade can help identify internal structures, cracks, or variations in density by observing how the light passes through the material.
