Each light source is activated by its own miniature on\/off switch. Because simultaneous use of the LED and UV lights is not practical, the loupe functions as either an LED loupe or a UV loupe at any given time.\u003c\/p\u003e\u003cp\u003eThe UV light has a wavelength of 380–390nm and is used for checking fluorescence in diamonds. Diamonds with fluorescence appear cloudy when viewed under the UV light. The white LED ring provides bright, even illumination for general gemological and jewelry inspection tasks.\u003c\/p\u003e\u003cp\u003eThe loupe is powered by three (3) L936 (Eveready 394) button cell batteries, accessed via a threaded cap that can be opened with a coin. Each loupe comes in a soft leather case packed inside a cardboard box.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e10X magnification with a 20.5mm diameter glass lens\u003c\/li\u003e\n\u003cli\u003eTriplet construction, three lenses bonded together for optical performance beyond doublets and single-lens designs\u003c\/li\u003e\n\u003cli\u003eAplanatic correction reduces spherical aberrations for a wider, edge-to-edge field of view\u003c\/li\u003e\n\u003cli\u003eAchromatic correction eliminates color distortion for true-color viewing\u003c\/li\u003e\n\u003cli\u003eTwo independent lighting systems: a white LED ring and a single UV light\u003c\/li\u003e\n\u003cli\u003eSeparate miniature on\/off switch for each light source\u003c\/li\u003e\n\u003cli\u003eUV wavelength of 380–390nm for diamond fluorescence evaluation\u003c\/li\u003e\n\u003cli\u003eBattery compartment secured by a coin-operated threaded cap\u003c\/li\u003e\n\u003cli\u003eSupplied with a soft leather case and cardboard box\u003c\/li\u003e\n\u003cli\u003eCustom imprinting available for orders of 100 or more\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eWhat you get:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e10X Triplet LED\/UV Light Loupe\u003c\/li\u003e\n\u003cli\u003eSoft leather case\u003c\/li\u003e\n\u003cli\u003eCardboard box\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTriplet:\u003c\/strong\u003e Three separate lenses bonded together, superior to doublets and single-lens magnification for clarity and field of view.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAplanatic:\u003c\/strong\u003e Corrected for spherical aberrations, providing a larger field of view from side to side.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAchromatic:\u003c\/strong\u003e Corrected for color distortions, enabling true-color viewing of gemstones and metalwork.\u003c\/p\u003e\u003cp\u003eBecause the LED light renders the UV light unusable when both are active, only one light source should be used at a time.\u003c\/p\u003e\u003cp\u003e\u003cem\u003e\u003cstrong\u003eCustom imprinting is available with a minimum order of 100 loupes.
