Fiber for Gemstone Identification SMA-DUVZB-02
Fibers support jewelry identification chiefly through spectroscopy. Fiber spectrometers analyze sunlight, LEDs, lasers, flat displays, plasma, gas discharges, flames, stimulated emission, chemiluminescence, and other sources. Small flexible probes also enter fine gaps/interiors, collect reflected signals after illumination, and transmit them to optoelectronic analyzers. Spectrometers identify gemstones/jade, deriving type/quality from fiber-delivered spectra. Fast nondestructive tests are described as resisting electromagnetic, moisture, and corrosion effects. CCD arrays collect scans without moving gratings, reducing measurement time. Better accuracy/efficiency supports the jewelry industry. Uses include physical properties, color, inclusions, and fluorescence. Multiple analyses help determine authenticity/quality. Fiber choice depends on task. Silica advantages: broad UV-to-NIR transmission, heat resistance, and chemical stability. Uses: precise refractive-index/color/fluorescence analysis with high spectral resolution/accuracy, plus internal inclusion/crack signals. Plastic advantages: lower cost, softness, and bending for confined spaces. Uses: basic illumination/observation, with loss/bandwidth limitations for precision analysis. Glass advantages: high transmission efficiency over longer distances and good mechanical strength. Uses: remote source delivery or collection of reflected gemstone spectra. Choose by precision, resolution, band, cost, flexibility, and durability, sometimes combining fiber types for different needs.
