From works of art to tools of entry
The tools used by criminals leave a number of traces whose criminological applicability is comparable with a fingerprint. Often traces of this nature allow a tool used in a crime to be matched precisely. The size of traces goes down into the nanometre range. With the use of µsurf 3D technology, it is possible to determine fine microstructures with precise measurement data; and to store it in databases. Renowned police authorities, such as the FBI and its German counterpart the BKA, therefore use µsurf systems successfully for comparative examinations of objects used in crimes. NanoFocus technology is also used across the world for authentication of objects of art.
Tools of entryComparison of traces of impressions left by a tool of entry. By comparing traces created in the laboratory with the original traces (correlation technique), the tool of crime can be assigned to a particular crime.

Explosivesµsurf technology allows the comparison of the surface features originating in the production of materials in the explosive. Matching known surface data with the object found can help establish the origin of the material.

ProjectileThe signature of a fired projectile consists of a multitude of ultra-fine impressions. These are formed on the projectile in the barrel of the weapon when it is fired. Comparison between the projectile fired in the laboratory and the projectile found can clarify whether a projectile originates from a particular weapon.

Objects of artThe microstructure of a brushstroke on a painting is as unique as a fingerprint. In contrast to the time consuming lab techniques using samples which damage the painting, µsurf optical measurement allows for a quick and precise authenticity test. It is almost like recording and saving a fingerprint.
