UV-MULTISPEC for All Longwave and Shortwave UV Fluorescence Tests
The MULTISPEC UV Lamp LW/SW is a powerful professional tool designed for analyzing longwave and shortwave UV fluorescence in diamonds, gemstones, and minerals. Equipped with two parallel 4-watt UV tube lamps, it delivers both 366 nm longwave UV and 254 nm shortwave UV at high intensity—ideal for precise fluorescence testing in laboratories, trade environments, and educational settings. The UV filter with an output area of 70 × 45 mm ensures a clear and high-contrast display of fluorescence colors. Each UV lamp can be switched on individually, with a red indicator light providing maximum safety and ease of use.
After a short warm-up period, the MULTISPEC reaches its full UV intensity. For reproducible results—especially when evaluating diamond fluorescence—a consistent distance between the UV filter and the test object is essential. When used together with the UV-D/GIA dark chamber, professional testing conditions according to international standards such as GIA can be achieved. The durable UV fluorescent tubes offer a lifespan of approximately 3,000 hours, ensuring long-term reliability.
Its compact design, low weight, and robust construction make the MULTISPEC UV lamp an indispensable instrument for gemologists, mineralogists, laboratories, and dealers who require maximum precision in UV fluorescence testing. Manufactured in Germany and equipped with modern EMC-compliant electronics, it meets all requirements for professional UV analysis devices.
