• Triple-Spectrum LED System Engineered for professional gemologists, this flashlight features three independently controlled LEDs: white (3000K-6500K adjustable), yellow (590nm), and violet (365nm). The white light’s stepless dimming function enables precise clarity inspections, while violet light highlights fluorescence in diamonds and jade. Yellow mode enhances contrast for detecting inclusions in amber or pearls.
• Dedicated Control Interface Three tactile buttons allow instant activation of each light mode without cycling through settings. White and yellow lights offer smooth brightness adjustment via a sliding switch, maintaining consistent output even at low battery levels. Separate circuits prevent color interference, ensuring accurate readings during prolonged use.
• Professional-Grade Light Focusing Includes a detachable aluminum alloy concentrator tube that narrows the beam angle to 15°, increasing luminous intensity by 300%. The focused output penetrates thick gemstones up to 30mm, revealing internal fractures or layered structures. Recessed lens design protects against scratches during field work.
• Integrated Measurement Scale A -etched stainless steel ruler (0-60mm) along the provides on-the-spot dimensional checks for prong spacing, stone diameters, or setting depths. Graduations at 0.5mm intervals ensure ±0.2mm accuracy, eliminating the need for separate calipers during appraisals.
• Rugged All-Metal Construction Machined from aircraft-grade aluminum with Type III hard-anodized coating, the housing withstands repeated drops onto concrete from 1.5m. Threaded O-ring seals at joints provide splash for outdoor use. Weighing 4.2oz with included AA batteries, its compact 5.9” length fits in tool rolls or jacket pockets.
