ESDA®2
The industry-standard electrostatic imaging system for detecting indented writing
ESDA® works by creating an electrostatic image of indented writing, which is then visualized by the application of charge-sensitive toners. The sensitive imaging process reacts to sites of microscopic damage to fibres at the surface of a document, which have been created by abrasive interaction with overlying surfaces during the act of handwriting.

foram®3
785nm Raman Spectrometer for Forensic Applications
Fast, non-destructive and highly effective, Raman spectroscopy is an ideal technique for identifying and comparing substances of forensic value.
Unlike other Raman systems, the foram3 has been developed specifically for forensic examinations and includes dedicated casework management software providing automatic spectral comparisons and data archiving with search and match facilities.
The foram3 can be further enhanced through the addition of a comprehensive library of forensic Raman spectra for the identification of unknowns.
