Crime Scene Solutions
foster+freeman light sources and imaging systems blur the lines between CSI and laboratory equipment and make it possible for CSI’s to perform ever more complex examinations of evidence at the scene.
The benefits of examining evidence in-situ are numerous and include, the ability to produce rapid on-the-spot results, the prevention of backlogs caused when large amounts of evidence are submitted to the lab, and the option to examine items that are too big or otherwise unable to be returned to the lab.
“Forensic imaging technology meets powerful multi-spectral illumination to provide a complete solution to the search, detection, and capture of evidence”
Crime Scene Products
New additions to the foster+freeman Crime-lite range enable examiners to streamline investigations by combining illumination, imaging, and analysis tools within a set of instruments that close the gap between the crime scene, incident room and forensic laboratory.
Crime-lite® AUTO
Detect more evidence using the all-in-one forensic search tool

Crime-lite® X
A complete ALS kit in a single light source
LEARN MORE
The Crime-lite X enables the examiner to seamlessly switch between White, UV, Violet, Blue, Blue/Green, Green, Orange, Red, and Infrared LEDs, to perform a comprehensive multi-spectral examination of a crime scene.
Operated via a simple 3-button interface, the Crime-lite X provides new functionality, never seen before in a forensic light source, that will ensure that crime scene and laboratory examiners reveal the maximum amount of evidence in every examination.
Crime-lite®LASER
Ultra-narrowband LASER illumination from a truly portable light source
LEARN MORE
Available in Blue (447nm) and Green (520nm) wavelengths, the Crime-lite LASER is a handheld, lightweight device
capable of providing the intense illumination required to reveal every last trace of forensic evidence including, latent (untreated) fingermarks, body fluids, and potentially
hazardous CBRN materials.
- Accurate 2nm bandwidth improves evidence yields
- Triple-interlocked Class 3B LASER safety features
- In-built functionality includes self-test diagnostics and dark adaptation (operator readiness) features
- Optional full-face respirator LASER viewing goggles
Crime-lite CSI
Detect Every Last Trace of Evidence
Forensic or Alternate light sources (ALS) are widely used by investigators for the detection and examination of evidence at the crime scene.
While white (visible) light sources are used for the general search of a scene, examiners must utilise the full forensic spectrum (using narrowband illumination from the UV through to the Infrared) if they are to reveal every possible trace of evidence.
Fluorescence Examinations
Many materials and substances of evidential value possess a property called fluorescence. Fluorescence occurs when light of one wavelength strikes an object, and the object returns light of a different higher wavelength (this is known as the Stokes shift). Because the returning light (fluorescence) is much weaker in intensity than the original light beam, examiners must use filters to allow the fluorescence to pass but block all other unwanted wavelengths of light. Such filters are available as evidence viewing goggles and as camera lens filters. The Crime-lite AUTO integrates both the light source and filtration with a live image of any fluorescence displayed on screen.
Fluorescence examinations may reveal evidence including:
- Body fluids (semen, saliva, urine etc.) are revealed using UV, Violet, or Blue illumination.
- Illicit drugs / Narcotics revealed using UV or Violet illumination.
- Suspect fibres fluorescence under a range of wavelengths across the spectrum.
- Chemically treated fingermarks. Many fingerprint treatments are designed to fluoresce under narrowband illumination to increase print visibility/contrast on a wide variety of surfaces.
Beyond Visible UV/IR Examinations
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 UV and IR light sources (all models) enable the examiner to search beyond the limits of human vision – in order to detect the presence of blood and other body fluids and to reveal fingerprints while significantly suppressing backgrounds.
While the search is typically invisible to the naked eye, examiners are able to reveal evidence via a specialist camera such as the Crime-lite AUTO or Crime-lite CAM.
Beyond visible examinations may reveal evidence including:
- Blood stains and spatter (even on dark substrates) using infrared examination
- Gunshot residues, using infrared examination
- Fingerprint treatments including cyanoacrylate, which can be photographed very effectively using reflected-UV imaging.
A fingermark is treated with BY-40 and examined under blue light
Semen can be seen to fluorescent under blue illumination
Reflected-UV reveals fingerprints on tape, fumed using cyanoacrylate
Cocaine fluoresces brightly when illuminated using a blue LASER viewed via 530nm bandpass filter
Blood is revealed using infrared imaging
