A UV Tester can be used to inspect the Fluorescence of e.g. stamps, banknotes, credit cards and more. You check the fluorescent authenticity characteristics of Banknotes to distinguish the original from the counterfeit or in the case of Postage Stamps checks the illumination of Phosphorus stripes or an L profile.

Postage stamps contain phosphorus to enable automatic sorting at the post office. The first stamps with phosphorus appeared in Britain in 1959 as a replacement for stamps with graphite. There are a large number of stamps available with and without phosphorus. It can be very useful to be able to make this distinction in your collection, and there is often a difference in value between the two. Some stamps from these countries have a different way of applying the phosphor, so the phosphor lights up with a different frequency. If you want to be absolutely sure, it can be helpful to use both long wave and short wave with certain countries.

You need the short wave at least for Great Britain, Israel and United States. There are 3 types of UV, namely UC-A the most common long wave, 315-400 nm, UV-B this is only used for other purposes, 280-315 nm, UV-C the short wave, 100-280 nm.

This handy UV Hand Lamp L81 combines two functions in one device. Stamps, banknotes, credit cards, phone cards, etc. can be checked for fluorescence and phosphorescence in equal measure. The combination of 254 nm (short wave) and 366 nm (long wave) makes the lamp extremely practical for the user. The UV hand lamp has a built-in filter against long-wave residual light.

The sturdy housing is black plastic, light weight and easy to carry. Supplied without batteries (4 x AA).
