Video Spectral Comparator HSC-VSC – Forensic Document Examination
Price on Request
Video spectral comparator for questioned-document examination: UV (254/312/365 nm), IR (880–950 nm) and visible light, 10×–100× magnification, Full HD live video, image capture and measurement software.
The HSC video spectral comparator (VSC) examines documents under ultraviolet, infrared and visible light at up to 100× magnification, so that alterations, forged entries, hidden security features and differences between inks show up on screen. It is used by forensic laboratories, banks, passport and security agencies, and quality-control departments that check printed documents.
What it helps you find
- Alterations and erasures: changes invisible in daylight often show under UV or IR.
- Different inks: two inks of the same colour can respond differently to infrared.
- Security features: UV-reactive fibres, inks and watermarks on currency, passports and certificates.
- Counterfeits: side-by-side comparison with a genuine document.
