According to the developers at Scanovis, brushes, powder and chemicals will soon be tools of the past for securing evidence at crime scenes. The company has developed a laser-based solution that, among other things, uses IR laser radiation to detect fingerprints at the scene of a crime, quickly making them visible in a 3D scan and recording them digitally. Decisive factors for this technological breakthrough are the precision of the results delivered by the laser scanner and the easy handling of the system. But how to adjust the optics of a system using a low power laser in the mid-infrared spectrum? Working together with Ophir's measurement experts, the company was able to combine different measurement methods to this end.
