 SM-01 3D
Noncontact systems with Cartesian coordinates based on the interferential method
This instrument is essentially made up of an optoelectronics measurement head connected to an X-Y translating system consisting of two motorized mechanical precision axes and a PC. The processing unit manages the movement of the text along the straight-line and also point-by-point plotting of the altimetric values of the surface. Three-dimensional maps are obtained by examining the area of interest along equispaced parallel lines. The graphisms being measured are scanned with a precision of less than one micrometer (for heights on the Z axis).
The axonometric results of the grooves generated by the graphisms and the surface alterations of the paper texture (where there are grooves) make it possible to objectify the chronological order of two superimposed graphisms.

 SPF
Reflectance Spectrophotometer
The reflectance spectrophotometer, called SPF, was made especially to operate directly in loco on the chromatic characterization of inks to, among other things, ascertain whether the same writing instrument (and consequently the same ink) as that used for the main text was used to make an addition or correction to it.
Operative method: comparison of spectral responses between two inks (see suspect additions of text in a will).
You can also ascertain whether the additions or corrections to the text were made at one time or at different times.
Assumption: if both writings were made simultaneously (and by the same hand), they are subject to the same environmental conditions and will dry in the same way; consequently the corresponding spectral responses will produce a similar result.
The instrument has a mega-enlargement capability in a spectral range from 360 - 1000 nm with a resolution of 2 nm. The results of the measurements are saved in the form of histograms with the relative spectral responses of the inks being examined. Moreover, for each portion of graphisms examined, an image is saved in order to be able to repeat the measurement at the same point of the document in cases of contention, further examinations, etc...

 MSM
Miniaturized multi-spectral microscope
Miniaturized multispectral microscope. This microscope has three different sources of illumination (which can be mixed with each other):
- White illumination
- UV illumination
- IR illumination
The microscope has two fixed magnification factors:
40X (for an object field of approximately 7.5x10 mm) or 140X (for an object field of approximately 1.8 x 2.5 mm)
A highly color-sensitive camera built into the microscope allows you not only to view and save images in certain DTP formats but also to take two-dimensional measurements of the digitalized images (after appropriate spatial calibration of the pixels with an engineering-level scale factor).
Examples of applications are given in the attached PDF file.

 MMB
Video comparator
Video comparator for document analysis:
The video comparison technique uses an illumination system called MMB. The MMB was specifically made to view anomalies created by fraudulent tampering with documents and acquire images from the areas of interest in digital format. The instrument makes it possible to conduct analyses in the following ranges:
Ultraviolet (using a UV LED source of light)
Visible (using an RGB LED source of light)
Near infrared (using an IR LED source of light).
Examples of applications are shown in the attached PDF file.

 STEREO MICROSCOPE XTS 01
The stereomicroscope XTS 01 was designed specifically for document analysis.
The instrument has a flat stationary support platform with a raised glass shelf for easy observation of documents in A4 format. The illumination set contains:
An illuminator with a dichroic spotlight transmitting cold light (white) through two metal sheaths having adjustable semirigid optic fibers;
A ring illuminator of diffused light (white) in high-frequency fluorescence;
An illuminator of diffused light (white) by means of an adaptable dichroic spotlight with adjustable intensity and direction.
Moreover, the trinocular head is mounted on a digital high-resolution color 1.3-megapixel 12-bit camera, including an USB II interface.
Additional illumination units are available (IR, UV), additional optical systems, polarizing filters, LED rings, etc.
