The Secrets of UV Pen and UV Spy Light Just For YouThe ultraviolet light has a wavelength extremely lesser than any of the visible lights. At its lower extremity, the frequency of UV light will be 1-30 nm. On the higher side, it rises up to 380 nm.Moving on to spy pen and UV pen light, a UV light pen is very much similar to a normal fountain pen (also called an ink pen), but uses special ink which will be visible only under high intensity UV light. This can be used to write on any paper surface, plastic, metal, or smooth skin. The ink dries in no time without leaving a trace. A UV ball point pen may also be used as a normal spy pen. The UV pens are used for secure writing of messages, phone numbers and diagrams which are intended to be secret. Purpose of UV Pen and UV Spy LightsThe two part UV pen and spy lights have many practical purposes. They are designed for occasions where use of open markings and writings is not practical. For example, in military messaging, there is always the risk of a mail or some letter falling into wrong hands. For the purpose of maintaining secrecy, the messages are written on plain papers, but with only this invisible ink.Traders and manufacturers use this technique for making hidden security markings which eliminates the risk of accidental removal of usual labels. The technique is also used when particular identification marks are needed to be made, which can be visible only under UV light. In one word, it is a compact and an inexpensive way of preventing secret codes, messages, phone numbers, diagrams etc. from being visible and identifiable. Features of UV Light Pen and the High Intensity UV LightSome of the manufacturers make their brands in two parts with the high intensity UV lights being a separate unit from that of the UV pens. Some other brands are available in one piece with built in UV light.The two part UV pen and light combination works on 2AA sized alkaline batteries housed on the rear side within a sliding top cover. To use the light, simply push the ergonomically located button. The light is compact and built in bakelite and matt finished on the external surface. The size is so compact that it can be carried in your pocket (2.5” x 3.5”.) It also features control buttons for varying the UV light intensity. It sports a clamp on the rear side by which you can clamp it onto your waist belt.
