At last an alternate light source that is small, cost effective and actually works for the detection of body fluids (semen, saliva and urine) and fluorescent powders.

When we talk about alternate light sources we are usually referring to the larger ones priced from $3,000 to $16,000. These are not easy to take with you to crime scenes on a regular basis.

If you do not have an alternate light source with you, chances are you would not go back to your office to get one. You would just do without it. The MicroBlue is a small penlight-size unit with a blue LED and amber shield will fit in your crime scene kit or even in your pocket. The unit is powered by 3 "AAAA" batteries and, yes, these are available through most places that handle batteries, such Radio Shack.

Though not as powerful as the larger units, it has its place because it is portable and cost effective to use. Latent fingerprints, which are treated with fluorescent fingerprint powder, usually have more detail than the same print developed with conventional methods. The MicroBlue unit will make semen, saliva, and urine fluoresce so it can be collected and sent to the lab for analysis. It will also illuminate some fibers.

Its wavelength is absorbed by blood making the blood appear black so that it can be easily seen and photographed. In some cases, if the room or area you are examining is bright it might be necessary to dim the lights to get the best results.

The MicroBlue light source is handy to use at rape or death scenes to view the body and the scene for any evidence that cannot be seen by the naked eye. It can also be used at the hospital to scan a victim for semen stains on the body. Placing an amber lens on the camera to capture the images or shooting through the amber shield enables you to photograph these stains and prints. A basic setting for your camera using 200 ASA film is to set the aperture at 5.6 and the shutter is set for a 2 second time exposure. Us your MicroBlue as the light source for these photographs.

The MicroBlue can be purchased through the Lynn Peavey Company.
