One of the forensic investigators most valuable tool is the forensic light source (also referred to as an Alternative Light Source (ALS)). From uncovering evidence that is poorly revealed, or even invisible by conventional light to indepth investigation of evidence, the use of high-powered multiple wavelength lighting is essential both in the field and forensic laboratory.
The effectiveness of forensic light sources such as the Foster + Freeman Crime-lite range can be put down to fluorescence, an optical phenomenon wherein a material absorbs light at one wavelength and emits light at a longer wavelength. Most organic materials can be made to fluoresce at a given wavelength, below is a list of just some of the evidence types that forensic light sources are routinely used to uncover:
- Fingerprints
- Body fluids including blood, saliva, semen etc.
- Trace evidence such as fibres’, glass, hair, paint etc.
- Gun shot residue
- Bite marks and bruises
At one time alternate light sources were so unwieldy that they were deemed to be unsuitable for use at the crime scene. Recent developments in technology has reduced the size of this vital piece of equipment to a handheld torch or flash light.
Foster + Freeman’s latest forensic light sources include:
