The UV-COLOURSCOPE is a device used primarily for examining the fluorescence of diamonds and other gemstones under ultraviolet (UV) light. It employs a specific type of UV lamp, typically a 9 Watt compact fluorescent tube with a 366nm wavelength (referred to as “Blacklight Blue”), to facilitate this examination. The device is particularly noted for its ability to conduct both transmitted and reflected UV light tests on specimens.
The main components and features of the UV-COLOURSCOPE include:
- Integrated miniature darkroom: This feature blocks out surrounding light, enhancing the visibility of fluorescence.
- Transmitted UV light testing: The specimen is placed directly on a black UV filter, which, in conjunction with the high-intensity UV light source, allows for the observation of even faint fluorescence, creating a high-contrast UV darkfield effect.
- Reflected UV light testing: A window on the underside of the device enables traditional reflected light observation of fluorescence, which is particularly useful when examining specimens still in their packaging. This specific wavelength is standard for testing diamonds and other gems.
- Switch: A switch on the front illuminates when the UV lamp is active.
- Flicker-free operation: This is achieved through high-frequency operation with an electronic ballast unit.
- Robust construction: Ensures a long service life.
Beyond gemstone analysis, some UV-COLOURSCOPE models also possess the capability to verify the authenticity of currency by illuminating UV-sensitive security features embedded in banknotes. These security features, often in the form of fluorescent strips or threads, glow under UV light, helping to distinguish genuine currency from counterfeits.
