Video Spectral Comparator-A Workstation for Questioned Document Examination

A video spectral comparator is an infrared video imaging system with CCD camera, 400 to 1100 nm wide range of interchangeable camera filters, five light sources for incident infrared light, transmitted white and infrared light, and incident long-wave ultraviolet rays; 6 element filter wheel to select a narrow wavelength between 400 and 700 nm and a handheld infrared pen torch.

This instrument is very useful in detecting alterations, comparing inks, identifying and analyzing watermarks, comparing paper, UV and Infrared imaging, and analysis of security features etc.

Electrostatic Detection Apparatus (ESDA)
-A Workstation to Develop Indented Writings and Impressions

The Electrostatic Detection Apparatus (ESDA) is a highly effective, non-destructive forensic tool that allows for the detection of indented writings or pressure marks on a document.

This instrument provides a more effective than traditional techniques like oblique light.

Digital Microscope – MiScope®

The MiScope combines a digital movie camera, precision optics, and LED lighting in a device. This device is designed to view live images on the computer screen with special features:

High magnification and resolution for detailed analysis

Completely portable.

Real-time imaging for immediate observation.

Built-in markers, time stamps, and measurement features.

Built-in visible and IR illumination to perform a visual spectral comparison.

Leica S6D Stereo Microscope

A stereo microscope provides:

Three-dimensional viewing for analyzing physical characteristics of documents.

Variable magnification for a detailed examination.

Enhanced depth perception to detect alterations and inconsistencies.

The wide field of view and great depth of field makes it an ideal instrument for determining the chronological sequence of intersecting lines, comparing the inks and detecting the alterations etc.

Ultraviolet Light Sources

An examination of a document under short and long ultraviolet rays can detect chemical erasing, alterations, substituted pages, and delicate stains due to artificial aging. UV rays are also useful in differentiating types of paper and sealing gums. This is a non-destructive technique.

Infrared Light Sources

Different inks absorb and reflect infrared light differently. Near infrared light can help to distinguish between inks of similar colors or types.

IR light can penetrate some layers of ink or pencil that might have been used to obliterate an original content. This method can reveal hidden or underlying text.

Out laboratory is equipped with various ultraviolet and infrared light sources and filters.

Digital Imaging System

Our laboratory is equipped with high-resolution flatbed scanners to capture detailed images of documents, including micro-text, watermarks, or subtle features.  Canon  and Sony SLR digital cameras to captures highly detailed close-up images of documents or small forensic details.

Digital Microscopes for photomicrographs, forensic imaging software and high-resolution laser and inkjet printers.

Dichroic, infrared, polarizer and color filters and ring light illuminator.
