Unique properties of the DIVA spectral camera and accessories

The DIVA mobile spectral camera is a portable, compact instrument for spectral imaging of historical artefacts and works of art. It is the only handheld spectral camera on the market that was specifically developed for the inspection, analysis and documentation of cultural heritage objects.

DIVA is ideally suited for on-site inspection, out-of-town jobs and short-term research visits. Using a battery-powered configuration (optional), the user is relieved from the hassle of running cables to the nearest mains power outlet and the system can be used in difficult-to-access places such as in ancient buildings or at field locations.
