Product Description

Checkpoint-DC Portable Compact Document Viewer. Nine Light Sources. Ideal for Passport Verification, Forgery Detection, and Border Security. Tough & Robust Construction. Top Quality British Made 

The Checkpoint-DC is a cost effective instrument for the examination of travel documents at border control points or for mobile patrols. Nine integral light sources allow the examination of most visual security safeguards found on the latest passports and visas, as well as offering the facility to check for alterations and additions to documents. Power can be from the local mains supply or from any 12 volt dc source, allowing the Checkpoint-DC to be used in patrol vehicles, and for transportation a padded carrying case is available as an option.


  • Overhead Incident White : Two lamps give even illumination of the working area for the visual examination of print quality and for checking for evidence of tampering
  • Overhead Incident Ultraviolet : Three wavelengths of ultraviolet illumination for the highlighting of security safeguards or for exposing alteration and staining. 365nm longwave Ultraviolet : 4 x 6 watt black light blue lamps (total lamp power 24 watts).313nm midwave Ultraviolet : A single compact 9 watt lamp with a narrow emission band at 313nm. 254nm shortwave Ultraviolet : A single compact 9 watt lamp. The 313nm and 254nm lamps are housed behind a special filter which blocks any visible lights from the lamps which might interfere with the highlighting of fluorescent security safeguards.
  • Transmitted Light  : Diffuse white : For even illumination of the whole examination area, principally used for the checking of watermarks. Spot white : M A single lamp giving an intense beam for the examination of obliterations and suspected photo substitution. Longwave Ultraviolet : Two 6 watt 365nm black light blue lamps for the highlighting of paper and printed security safeguards from the rear
  • Oblique : A lamp mounted at the rear of the examination area provides glancing illumination over the working area for the examination of erasures, dry stamps and indented writing.
  • Coaxial : A lamp to reveal retroreflective security safeguards in laminates. A narrow beam of light is reflected off the front window of Checkpoint-DCA to produce a beam onto the document which is coaxial with the operators eyes and so hidden images may be seen.
  • Intensity Adjustment : The overhead incident light, oblique, and coaxial lamps may be adjusted in brightness with a simple push button control


  • Magnifier : An integral 75mm circular magnifier with 3X magnification and with a local area of 6X magnification. The magnifier is attached to the Checkpoint- DCA with a chain so that it may be used anywhere inside or outside the examination area. This allows maximum flexibility not provided by a fixed position magnifier; when not in use the magnifier is stored on the side of the Checkpoint-DCA.
  • Loupe : A 10X stand loupe with a removable reticule for the checking of fine print and microprinting; the loupe is stored in a clip on the rear of the Checkpoint- DC when not in use or for transport.


  • 300mm (width) x 230mm (depth) - A4 size


  • The Checkpoint-DCA has a unique document holding feature which allows hands-free document examination. Two pairs of embedded magnets behind the transmission window are used with two flexible steel strips to hold documents firmly in place whilst being checked, particularly useful when examining open passport pages.


  • The front observation window is UV blocking so minimal UV radiation reaches the operator. In addition, the Checkpoint-DC has a hinged UV blocking window that switches off the 254nm and 313nm UV lamps when opened.


  • All the lamps are controlled from a single navigation switch assembly; a lamp is selected by pressing the up/down buttons and then pressing the OK button; the selected lamp may be switched off by either pressing the OK button again or selecting another lamp. The left/right buttons of the navigation switch adjust the brightness of the overhead incident light, oblique and coaxial lamps
