Crime-lite®

Beyond Visible

While a skilled investigator can learn a great deal through the visible examination of a crime scene, a great deal of evidence may remain unseen, hidden, or masked by the background.

Crime-lite® Beyond Visible is a unique range of products designed to search for evidence in the UV and IR wavebands - beyond the limits of human vision - in order to detect the presence of blood and other body fluids, and to reveal fingerprints while greatly suppressing backgrounds.

for the detection of blood on fabric

Such is the value of blood as forensic evidence, a source of DNA and often the vital link between suspect and crime, that fast and accurate detection of blood is a critical part of any investigation.

Crime-lite IR light sources allow the investigator to easily detect blood, even against dark backgrounds, without the need to use chemical reagents such as Luminol that may dilute samples and smear blood patterns.

 

 

 

for the detection of Gun Shot Residues (GSR)

During the past 10-years, crime scene examiners have become accustomed to using digital infrared photography as a non-destructive test for the detection of GSR at the crime scene. 

Using a portable Crime-lite IR kit, displaying live full-screen IR images, examiners are able to improve the efficiency of searches and detect more evidence of GSR than ever before.

for the visualisation of fingerprints

Created in-house by Foster+Freeman, fpNatural1 is a unique IR fluorescent fingerprint powder that enables examiners to reveal high contrast finger marks whilst suppressing background interference.

Evidence dusted with fpNatural1 is illuminated with blue or red light with fluorescence emitted in the IR region of the spectrum.

Using an IR pass filter to block out all other wavelengths supresses the background leaving a clear, high-contrast print.

Reflected-UV Imaging

reflected-uv-radiation

 

While UV fluorescence examination is a common technique, the use of reflected-UV is far less wide spread.

Using a camera equipped with UV Pass/Vis Blocking filter we are able to see UV illumination being reflected from the surface creating clear contrast against materials that absorb UV.

The technique can be used to detect the presence of fresh paint (which reflects UV) alongside aged paint (which absorbs), to improve the contrast of shoe prints in dust, and to reveal latent or superglue fumed fingerprints.

UV Illumination / 330-380nm Bandpass Filter

for the visualisation of fingerprints

In these examples, items of evidence have been fumed with cyanoacrylate before being illuminated with UV light.

The technique is particularly useful when imaging fingerprints on difficult surfaces such as curved glass.

Glass absorbs UV and appears black when viewed through the UV pass filter. This eliminates any reflections or interference that may have previously been seen through the glass - a filament on a glass light bulb for example.

  UV-VIS-IR Camera Attachment

This high specification digital camera can be attached to any Crime-lite forensic light source and enables the examiner to observe UV and IR wavelengths.

The live camera image is transferred via high speed USB 2.0 to a PC or tablet computer loaded with the Crime-lite Cam software package.

The cameras integral filter wheel allows the operator to quickly switch between UV Pass (Vis/IR blocking), IR Pass (UV/Vis blocking), Vis Pass (UV/IR blocking), and UV-Vis-IR Pass filters.
