Novel lens enhances forensic fingerprinting technique
Resolve Optics has supplied a custom lens to Consolite Forensics to optimise the performance of their Cartridge Electrostatic Recovery and Analysis (CERA) system.
The 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.
Resolve Optics ultra-compact Z10 HD mini zoom lens has been designed to complement small profile HD cameras.
New adaptor provides a true 0.5x field of view whilst maintaining minimal distortion and high resolution.
The Model 207 f/2.8 zoom lens is capable of focusing on an object positioned just 35mm ahead of it.
Resolve Optics has launched an expanded range of its Z10-HD lens at the International Broadcasting Convention.
Resolve Optics will be exhibiting at the VISION 2012 exhibition in Stuttgart on 6-8th November.
