Forensic Light Source Applications Wavelengths And Uses

Forensic light source applications.

Forensic light source applications wavelengths and uses.

Fibers gunshot residue biologic fluids pigments inks and fingerprints and different wavelength are used to better enhance the material characteristics. Wavelengths and uses fls applications. In addition to handheld crime lites foster freeman manufactures two models multi wavelength laboratory light source. Instruments such as forensic light sources reflective uv and fingerprint imaging systems are designed to be used at the crime scene to collect and in the laboratory to analyze evidence.

The use of fluorescent enhancement processes that compliment a light source greatly increases the types of surfaces from which a latent fingerprint can be detected. While the crime lite 8x4 is ideal for the visualization and enhancement of fingerprints the crime lite ml2 has applications including the detection of body fluids and marking up of evidence. An even more detailed use of infrared technology in forensics is infrared spectroscopy. It then filters down the light into individual color bands wavelengths that.

Uv blue lights locate bodily fluids trace evidence. The primary application of a forensic light source is for enhancing the detection of latent fingerprints. Cyan green light help with fingerprints. Applications detection of body fluids with an alternate light source.

Foxfury portable forensic light sources and lasers help visualize evidence and can be used in the field or in the lab. Each chemical bond within a molecule vibrates at a frequency that is unique to that bond much like a fingerprint. These substances are often not observable to the naked eye and especially if the surface was wiped down or cleaned. To eliminate the fluorescence of the cleansers or detergents use a forensic light source tuned above 440nm.

The proper colored goggle will block the specific wavelength of light emitted by the forensic or alternate light source allowing only the longer wavelength fluorescence to pass. In simple terms infrared spectroscopy is the use of infrared light to analyze the chemical bonds within molecules. Horiba manufactures forensic instrumentation to collect and analyze evidence during the course of an investigation. Many body fluids organic materials and fibers will fluoresce under the forensic light source and other materials such as blood gunshot residue and some inks will absorb blue light to appear dark under the light source.
