The VSC®8000 combines sophisticated digital imaging and multi-wavelength LED technology with a clear and efficient software interface, to provide a complete solution to the examination of all questioned documents.



 Examine documents

 Reveal hidden details

 Display UltraHD images



with advanced technology used and trusted by forensic examiners and immigration authorities worldwide

using a wide variety of examination facilities to observe security features and detect irregularities

using Super Resolution Imaging to display sharp, bright images of documents on a 4K UltraHD monitor





 System Features









the essential VSC workstation
for the examination of all documents


The VSC8000 provides users with an array of techniques for examination and authentication of all types of document.

Infrared, hyper-spectral imaging and the systems integral spectrometer may all be used to detect the use of multiple inks on a document, and in many cases, establish the order in which different inks were added to a page.






 SRI Super Resolution Imaging

Unique to the VSC8000, Super Resolution Imaging (SRI) is an optical system providing excellent clarity and image resolution of documents up to A4/Letter size.



Precision XY Stage

A motorised XY translation stage, with simple on-screen controls, allows fast and precise positioning of documents at high magnification.



Non-destructive spectral analysis of documents to identify differences in inks and paper formulation. 

Absorbtion, Reflectance, Fluorescence & Transmitted spectra are captured in real time and displayed on-screen in a simple graphical format.






multi-spectral illumination

Multi-spectral illumination

Directional, multi-spectral light sources from UV through the visible spectrum, to IR can reveal details that are normally invisible to the eye, increase image contrast and excite document security features.



Hyper-Spectral Imaging

An advanced technique for the discrimination of inks. Incremental images of documents are captured across a broad spectrum. A false colour overlay highlights spectral differences.




user centred system design

User-Centered Design

At each stage of the VSC8000 design process, attention has been given to the requirements of the end user. Many of the system's new features come as a direct result of user feedback.



 System Features






examine & authenticate
all types of questioned document 


Designed to meet the requirements of immigration authorities, government agencies and forensic science laboratories, the VSC8000 includes advanced features for the examination, comparison and authentication of documents including passports and travel documents, official letters and breeder documents, banknotes and cheques, works of art and valuable artefacts through the detection of irregularities.

Valuable Artefacts


Visual examinations of a document under high magnification can quickly reveal physical evidence of tampering while examinations under various wavebands of illumination can expose alterations. The VSC8000 is capable of revealing all levels of security features including covert features such as anti-Stokes inks, latent images, UV security threads and taggants.


Non-destructive VSC examination makes it  possible to establish the authenticity of an item, detect changes that have been made and to see beneath the surface of an artifact revealing its history.

Intelligent Software

Introducing VSC Suite 7.0


At the heart of the VSC8000 is sophisticated software that maximises the effectiveness of document examinations by providing the user with complete control of all VSC functions via a quick-access toolbar.


Document specific workspaces

Document Specific Workspaces

A range of application focussed workspaces provide tools and functions specific to the type of document being examined.

Pre-set workspaces include: Passports, ID cards, banknotes and handwriting analysis.



Automated Examinations

Predefined procedures greatly increase both the speed and efficiency of examinations.

Results are displayed and stored together with VSC examination settings.


Calibration & Diagnostics

To ensure accurate and repeatable results, the system can be calibrated using NIST traceable standards.

Reliable system performance can be verified using simple automated diagnostics to check the status of motors, light sources and filters.
