DCS 5 reveals fingerprints on a densely patterned banknote dusted with fpNATURAL 1, Foster + Freeman’s new IR fluorescent po

DCS 5 is a comprehensive imaging system for the detection, capture and enhancement of almost any type of fingerprint on any surface or background to ensure that maximum detail is revealed. Not only does the DCS 5 high resolution camera (fitted with application specific macro lenses) produce images of exceptional quality, advanced digital enhancement, applied simply, maximises print detail to improve the value of evidence. Precise wavebands of illumination from UV through the visible to IR are provided to improve the visualisation of every type of fingerprint whether it be latent,...

Imaging Techniques Fluorescence Imaging Many latent fingerprint treatments such as Ardrox, DFO, BY40 and fluorescent powders fluoresce under specific wavelengths of light. Using the DCS 5 multi-wavelength ring light an operator is able to select the optimum wavelength to generate the maximum intensity of fluorescence for each type of treatment. Plastic bag treated with Polycyano UV and examined under UV illumination. VISIBLE FLUORESCENCE INFRARED FLUORESCENCE ‘UNWRAPPED’ IMAGE Infrared Imaging Interfering backgrounds may be suppressed appearing white as they reflect IR whereas some chemical...

Enhancement Software Digital Enhancement An integral part of DCS 5 is the easy-to-use software that provides sophisticated image processing and enhancement tools to uncover hidden detail within images. Operated via simple drop down menus, DCS 5 enhancement software enables the operator to remove textured or ‘difficult’ backgrounds as well as enhance prints developed using a variety of chemical treatments, dyes, stains and dusting powders including the new IR powder. Each toolbox offers the operator ‘tried & trusted’ enhancement programmes that enable complex processing routines to be...

System Components custom-modified digital SLR camera In order to achieve excellent image quality, the DCS 5 has been built around a pro-grade DSLR camera customised by Foster+Freeman for UV-Vis-IR imaging applications. Nikon’s full-frame flagship camera, the D5 takes advantage of huge advancements in sensor design to deliver images of exceptional clarity across the spectrum. Lenses A choice of specialist lens provides greater control of the image captured by the camera. 2 2 105mm Vis-IR Macro Lens for general imaging Focusing up to 1:1 life size in auto or manual focus modes images remain...

System Components 1 Multi-wavelength Ring Light The Crime-lite 8x4Mk2 provides intense white, UV, violet, blue, blue/green, green, orange and red narrow waveband light for visible and fluorescent image examinations. 2 Halogen Light Source Package Intense 150W light source with 5 coloured filters for general contrast imaging. To be used in conjunction with the fibre optic light guides for directional lighting on any surface type. 3 Forensic Light Source (FLS) A continuous 400-1000nm narrowband light source used in conjunction with the fibre optic light guides provides specific wavelengths of...

In order to accommodate the differing requirements of fingerprint laboratories worldwide, DCS 5 is a modular system that can be expanded through the addition of application specific modules. The DCS 5 core provides a complete solution to the capture and enhancement of fingerprints within the visible spectrum and includes a Windows PC running the DCS 5 Software, a pro-grade photographic copy stand and a selection of light guide clamps and mounts. Additional modules can be selected to provide IR, Reflected UV and Shift/Tilt Imaging capabilities. DCS 5 core image capture Nikon D5 -...
