UV LED

Ultraviolet (UV) LED lights emit a light that is nearly invisible to the naked eye, but has many practical applications. UV lights can be used to authenticate documents like driver’s licenses, passports, credit cards, and currency, all of which include watermarks that are visible under UV light. Using this light, an individual can quickly scan any form of identification or currency. For art dealers, jewelers, and collectors, it also can highlight variations in fluorescence to determine whether artwork, gems, and artifacts are genuine or have flaws that would lessen their value.
