FOCUS LED Alternate Light Source

The FOCUS's superior optical design offers an homogeneous spot and defined edge to provide the consistent intensity necessary to properly capture photos where there are no under/over developed sections in the same image.

Segment: Scientific
Division: Forensics
Manufacturing Company: HORIBA Scientific

Use & Benefits

The FOCUS’s homogeneous spot and defined edge provides the consistent intensity necessary to properly capture photos where there are no under/over developed sections in the same image. Now the tightest of locations, at any crime scene can be searched with the same uniform illumination as that of a larger lab based light source. Compact and light weight, the FOCUS is the ideal tool for every examiner.



The FOCUS fits in the palm of your hand.  Its ultra-compact size is deceiving when it is illuminating a scene.   The superior optical design behind the FOCUS maximizes beam projection.  No other LED on the market can offer such a ruggedized unit and produce the same results. 


Extremely lightweight LED with a minimum 2 hours of run time, the FOCUS is an excellent choice for crime scenes where battery power is a must.  A single FOCUS can slip into a pocket or be easily transported in its rigid, water resistant case with its full line of accessories and other user-friendly LED units, for a total of 6 available wavelengths.

Ease of Use

The FOCUS, with its push button instant on, will not delay the processing at a scene.  The unique design, with its 6 sided hilt, serves 2 purposes: displaying the wavelength and not rolling away.  The attached lanyard helps keep the FOCUS from becoming a statistic, by keeping the unit attached to the wrist, helping to avoid the accidental drop.

FOCUS LED can easily detect biological fluids and trace evidence, treated fingerprints, gunshot residue, drugs, bite marks and footprints.  It can also be used to find hair, fingernails, bones and teeth.

Detection of Body Fluids with an Alternate Light Source
Detection of Body Fluids with an Alternate Light Source
Since body fluids like semen, saliva, and vaginal fluids are naturally fluorescent, the use of a light source offers a unique method for locating them. A crime scene investigator can narrow down the specific locations of stains for collection instead of testing entire, large pieces of evidence such as a mattress, a carpet, a sheet, an article of clothing, etc. The dried body fluids will actually glow under the light source illumination.
Bruises, Bite Marks and Pattern Wounds
Bruises, Bite Marks and Pattern Wounds
On some individuals, a tunable or multiple wavelength forensic light source may reveal bruise and patterned wound details that are invisible under normal white light illumination.
Detection of Gun Shot and Explosive Residues
Detection of Gun Shot and Explosive Residues
There are several different types of residues found both in ammunition and explosives, which fluoresce. By using a tunable Forensic Light Source, observations can be made on items without touching the surface, to see if fluorescent residues are present.
Detection of Trace Evidence
Detection of Trace Evidence
Forensic and Alternate light sources are useful tools to detect both fluorescent and non-fluorescent trace evidence.
