New examination system for passport authentication

Foster & Freeman have added a new document examination system to their range. The new instrument, called VISPEC, has been designed for the examination of standard security features in passports and travel documents by immigration authorities.

Facilities available in VISPEC include incident and transmitted visible illumination, long and short wave incident UV illumination, transmitted long wave UV illumination, co-axial lighting, for examining retro-reflective features, and oblique illumination, for examining embossed stamps and assessing the quality of intaglio printing. Unlike the company's other document examination systems, however, VISPEC is not equipped with an infrared imaging capability. Other applications for the system include the authentication of banknotes and identity cards with similar security features.

As a video based system, VISPEC offers a bright, high contrast display, zoom magnification with close-ups to ×38 on the standard 14" monitor, image overlays for visual comparisons and hard copy via an optional video printer. Fields of view range from 8×6mm to 115×90mm.
