Dual-Wavelength UV Lamp for Accurate Stamp Examination
One of the easiest ways to determine the authenticity of stamps is with ultraviolet (UV) fluorescence. The Spectroline® ENF-240C dual-wavelength UV lamp is a powerful and reliable tool for uncovering errors in tagging, repairs, inconsistencies or forgeries.
The ENF-240C features two 4-watt tubes, one that emits long-wave UV (365 nm) and another that produces short-wave UV (254 nm). A special LONGLIFE™ glass filter resists solarization and ensures optimum UV output. A dual-wavelength light source is recommended for philately since some foreign stamps fluoresce best under long-wave UV while others, such as U.S. stamps, fluoresce most effectively
under short-wave UV.
Measuring only 3¼W x 8L x 2½”H (8.3W x 20.3L x 6.4cmH) and weighing just 2 lbs. (0.9kg), the ENF-240C is lightweight and compact. It has a rugged housing made of anodized aluminum and comes with a convenient carrying handle. The ENF-240C can easily slide into the SE-140 lamp stand for hands-free use, or can be used
with the CM-10 viewing cabinet for increased fluorescence, both available as accessories. |
