TrasoScan Applications

TrasoScan System is a completely versatile solution for scanning, examination, and comparison of all kinds of forensic evidence including:

  • Shoeprints (black / white / transparent foil).

  • Fingerprints (direct visualization, or treated with typically used powders).

  • Shoe soles, documents, and various other objects.

System Provides

  • Versatile multispectral illumination in 6 pairs of LED panels, true RGB scanning available.

  • Motorized autofocus guarantees 1000 DPI resolution regardless of object thickness.

  • Real-time camera image – 100 x 70 mm area at fixed 1000 DPI resolution.

  • Scanning of area up to 400 x 210 mm at 1000 DPI resolution.

  • Scanning of objects of a height of up to 22 cm.

  • All accessories, filter holder, and a vacuum pump.

  • Complete software integration, all tools for image processing, comparison, measurement, annotations, and reporting.
