Regula 4308 Dual-video spectral comparator
The device is made as a single unit for desktop use. It is used with a built-in PC (may be connected to an external PC via USB 3.0) and fully controlled through «Regula Forensic Studio» software interface (supplied with a unit). The device is equipped with a high resolution spectrometer, hyperspectral imaging module, light source for anti-Stokes luminescence, XY translation stage, modules for reading MRZ, RFID chips, hidden image (IPI), 1D and 2D barcodes.
Being the best in class for advanced document examination, Regula 4308 has been developed and produced with the use of the latest hi-tech innovations.
Its high functionality is achieved due to over 30 types of light sources, over 20 light filters, a self-developed precision optical system and 2 high-resolution cameras.
Advanced system for capturing high-resolution images preserves all tiny elements precious for further object examination.
New algorithms and the enhanced optical scheme make it possible to obtain a multi-focus image in one click. Such an image takes on a new level of detail as the whole frame turns out to be in focus independent of the size of its relief.
