A collaborative study between foster+freeman and L’Institut de Recherche Criminelle de la Gendarmerie Nationale (IRCGN).
The Crime-lite product range is suitable for the detection and visualisation of different types of drugs residues. This application note examines a variety of different drugs residues/adulterants under various light wavelength/filter combinations.
The use of bandpass filters with light sources may reveal evidence which was undetectable with the use of a standard longpass filter. Bandpass filters can also increase the contrast between evidence and substrate to better analyse its morphology.
foster+freeman have been granted a licence by the Human Tissue Authority (HTA) for the storage of biological materials, which have come from the human body, for research, education and training purposes.
Using Infrared light we can exploit the differences in absorption and reflection between substrate and evidence to reveal otherwise hidden information.
In a paper published by New Scientist, foster+freemans’ Dr Roberto King outlines a new technique that could be important in cases of fraud.
Longwave Reflected UV for the Enhancement of Cyanoacrylate Fumed Fingerprints Research conducted by Foster+Freeman, has added further weight to the argument that Longwave Reflected-UV (LWUVR)…
Visualising Fluorescent Fingermarks Developed Using 1,2 Indandione A study has demonstrated that by trimming the illumination wavelength and narrowing the viewing bandwidth, markedly better results…
