What Happens When You Shine 365nm UV Light on Banknotes?
Ultraviolet (UV) light at 365 nanometers (nm) isn’t just for counterfeit detection—it’s a gateway to uncovering the mesmerizing hidden artwork and security features embedded in modern banknotes. Collectors worldwide use UV light to reveal fluorescent designs, secret threads, and anti-fraud elements invisible to the naked eye. In this guide, you’ll learn how to start your own UV bill collection and appreciate the science and artistry behind currency.
Why 365nm UV Light? Understanding the Science
Not all UV lights are equal. The 365nm wavelength falls within the “longwave” UV spectrum (UVA), which is safe for brief use and perfectly calibrated to interact with special inks and materials in banknotes. These security features fluoresce (glow) under 365nm light, creating vivid colors like greens, yellows, reds, and blues. Shorter wavelengths (e.g., 254nm) may damage materials or fail to trigger fluorescence, making 365nm the gold standard for collectors.
Glowing Secrets: What UV Light Reveals in Banknotes
Under 365nm UV light, banknotes transform into miniature light shows. Here’s what to look for:
-
Fluorescent Fibers & Threads
Many currencies embed glowing threads. For example:- US Dollars: Security threads glow specific colors (e.g., $5 notes shine blue, $20s green).
- Euros: Red, blue, and green fibers scatter across the note like stars.
-
Hidden Images & Patterns
Invisible inks create covert designs:- Australia’s polymer notes reveal landscapes.
- Indian ₹500 notes display a floral motif.
-
Watermarks & Serial Numbers
Some watermarks fluoresce, and serial numbers may glow under UV. -
Anti-Counterfeit Safety
UV light exposes fakes lacking these intricate features.
