When viewing objects through the microscope with weak lighting, (for example: when using darkfield or fluorescence applications) the image signal can be enhanced by using the "Gain" slider control in the CapturePro Software. This allows the exposure time to be reduced in order to achieve the highest refresh rates as possible for displaying live images. It is important to note however that using "Gain" will result in an increase in background noise within the image.

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.

Analog gain offers higher sensitivity and less noise than using only digital gain. The result: higher refresh rates, higher sensitivity and less noise.

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.

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.

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.

The analog gain will increase sensitivity up to 8 times. As this takes place directly in the camera, the image signal is enhanaced through the use of analog gain upstream of the ADC in the camera, and the background noise is reduced at the same time. Hence, the analog gain offers higher sensitivity and less noise than using digital gain only.

Bondhus (US made) are the best, but also Wiha (Germany made) are very good.

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.

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.
