The device is made as a single unit for desktop use. It is used with a PC (model Regula 4307MC.XХХХ is supplied with Built-in PC) and fully controlled through "Regula Forensic Studio" software interface (supplied with a unit). The video spectral comparator enables to capture, process and store digital images of examined objects. All models are equipped with modules for reading RFID chips, hidden image (IPI), 1D and 2D barcodes. Regula 4307 is supplied with a Spectral luminescent magnifier Regula 4147, information reference systems "Passport", "Autodocs", "Currency" (Brief versions).
Regula 4307 has a set of light sources of visible, infrared, ultraviolet spectral ranges and imaging filters used for carrying out forensic examinations.
The comparator can optionally be equipped with a hyperspectral imaging module, a high resolution spectrometer, a light source for anti-Stokes luminescence, an XY translation stage, a built-in PC.
