Latent fingerprint detection





EVISCAN is the first high-tech workstation to detect latent prints and trace evidence


EVISCAN is an innovative high-tech workstation that enables forensic experts around the world to detect, enhance and digitally preserve latent fingerprints and latent trace evidence. EVISCAN acquires latent fingerprints with neither physical contact nor use of chemical agents. The fingerprint residues are literally scanned and transferred into a built-in image enhancement software. Substrates, fingerprints and DNA remain 100 % in their original condition and therefore can be re-examined – even years later.

Developed in cooperation with German Criminal Police Offices to engineer a high-quality product that fits the requirements of today's crime scene investigation - made in Germany.

How EVISCAN works.


High-Tech for Forensics

EVISCAN is the first high-tech workstation to detect latent prints and trace evidence



For more than 100 years, dactyloscopy is an indispensable aid in crime solving. Since the late 19th century, fingerprints are utilized as means of identification. To detect and visualize latent traces, forensic investigators typically use a range of different techniques – including many relying on adhesives, chemicals and UV excitation. While such techniques can be highly effective, they require surfaces to be physically contacted in ways that ultimately can alter them. Altering of substrates or fingerprints, in turn, can hinder the use of other forensic technologies such as touch DNA or future innovations in fingerprint analysis.


Non-contaminative and non-invasive

EVISCAN acquires latent trace evidence with neither physical contact nor use of chemicals. The unique lab workstation combines the latest detector technology with cutting-edge software for processing digital images. Thus evidence remains available for all subsequent analyses, in its original condition and with its DNA material fully intact. And because no chemicals are involved, examinations do not endanger the health of the user.


Innovation for forensics

With EVISCAN, therefore, forensic investigators can examine objects thoroughly and still retain all other analysis options, thereby improving their chances to achieve an identification. Further, because EVISCAN no longer requires the time-consuming sub-steps of pre-treatment, exposure time and photo documentation, it reduces total processing time from hours – or even days – to just minutes. The acquired digital trace images can be immediately transferred to fingerprint databanks (e. g. AFIS) and dactyloscopic identification.

Excellent Results

One solution for various materials

EVISCAN acquires high-quality digital images of prints from a broad variety of relevant non-porous and semi-porous surfaces. Metals, pottery, glass or plastics can be processed even when they are wet, sticky or dirty. Even latents completely invisible to the human eye, e. g. trace evidence covered with black layers of soot, can be preserved with EVISCAN with no necessity to even touch the exhibit.
