Document authenticity verification device Regula 4105

The device is designed for express authenticity verification of banknotes, revenue and special stamps, securities, passports, ID cards, travel documents, visa stamps and seals, including but not limited to entry permits, driving licenses, vehicle registration certificates and other documents with security features.

Regula 4105 is designed as a small size unit in plastic body. Light sources for different examination modes are activated with the help of control buttons located in front of the object stage. A measuring scale on the light transmitting screen should be used for measuring sizes of examined objects. The device is equipped with a built-in infrared sensitive camera displaying an image on the monitor.
Product design provides a possibility to place a 10x magnifier Regula 100Х right on the device body.
