Optimised UV-Visible lens for crime scene investigation – Resolve OpticsThe Model 228 lens from Resolve Optics has become an industry standard for Reflected Ultraviolet Imaging Systems (RUVIS) used to detect fingerprints or bloodstains undiscovered during an initial crime scene investigation.

Collection of evidence, after a crime has been committed, is essential to establish facts associated with the crime and identify potential suspects. Traditionally law enforcement officials have relied on their eyesight and evidence collection methods, such as lifting fingerprints with tape, which are prone to errors or omissions. These techniques are being replaced by crime scene investigators using RUVIS camera operating in the deep UV (320 – 400nm).

The Model 228 lens offers many advantages to RUVIS scope manufacturers and crime scene investigators both in terms of performance and ease-of-use. This unique lens provides high performance in both the UV and visible wavebands enabling investigators to identify and focus on a target in the visible and then quickly slide the UV filter across to take images in the UV without having to refocus.

By using a telescopic focusing mount the Model 228 lens offers a large movement in an extremely compact form. This unique lens offers a true high-resolution crime site macro viewing capability by imaging onto a RUVIS scope with a 1:1 lens magnification whilst exactly matching the optical resolution of both lens and image intensifier. Designed to provide a wide field of view the Model 228 lens is widely deployed in RUVIS scopes used to produce macro images for fingerprinting and human skin damage applications.
