Resolve Optics Ltd. has supplied a novel custom lens to Consolite
Forensics Ltd. (Zeals, UK) to optimise the performance of their Cartridge
Electrostatic Recovery and Analysis (CERA) systemThe revolutionary CERA
technology is now able to extract fingerprints from discharged cartridge cases,
not visible by any other means.
The scenes of many crimes involving firearms, where spent cartridge cases are
the only evidence recovered, has traditionally posed a particular challenge for
forensic scientists. Using fingerprints, caused by corrosive sweat, on brass
metal cartridge cases has enjoyed some recent success in producing identifiable
fingerprints* where conventional techniques have failed.
After insertion of the spent cartridge case the Consolite CERA system starts
out by automatically measuring the size and shape of the casing, and then
distributes a powder over the surface in a uniform and carefully measured way.
The powder is attracted to areas of surface corrosion caused by chemicals in
the fingerprint deposit. Once a clear print is obtained the CERA camera, fitted
with Resolve Optics lens, collects a number of high resolution images from the
circumference of the cartridge and downloads them to special imaging software
to create a fingerprint for identification.
Mark Pontin, Managing Director of Resolve Optics commented "Consolite
approached us to develop a custom lens to provide the correct magnification and
the required depth of field for their CERA system to optimally operate.
We worked closely with Consolite to ensure the special lens we developed
provided a 10 megapixel image and maintained the correct geometry free of any
optical distortions".
