Portable Document Examinator 4305M, 4305MH, 4305DMH

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

The comparator is constructed as a single unit for desktop use in aluminum metal body. It is equipped with a built-in RFID reader. The device has a spacious working area over the object stage, clamps for fixing examined documents and a special shield protecting from harmful effects of ultraviolet radiation.
The device is operated via the front panel with control buttons or/and Regula Forensic Studio software. The control buttons are responsible for the activation of light sources and adjustment of camera parameters in different examination modes. The latter are displayed on the LCD display.
To enhance document examination, use the comparator Regula 4305M/MH with the following devices: a spectral luminescent magnifier Regula 4027, a UV bottom lighter, a magneto-optical visualizer Regula 4098 (optionally). Product design provides a possibility to place a 10x magnifier Regula 100Х and a torch right on the device body.
Video spectral comparator Regula 4305DMH is equipped with a torch and a modified 10x magnifier Regula 1003M with two white light sources. The front panel of the device has a port for connection of a UV bottom lighter, three available USB-2.0 ports — for additional external devices, such as a spectral luminescent magnifier Regula 4147 used in anti-Stokes examination, or a magneto-optical visualizer Regula 4197.
