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 a hyperspectral imaging module, modules for reading MRZ, 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 high resolution spectrometer, a light source for anti-Stokes luminescence, an XY translation stage, a built-in PC.
