TracER Crime Lab Laser

For Trace Evidence Recovery, Including Latent Fingerprints
SANTA CLARA, Calif., May 15, 2006 - The new TracER laser from Coherent Inc. is a powerful tool for trace evidence recovery at crime scenes, including latent fingerprints, the company said.

Based on a 5-W green laser, TracER lowers the barrier to laser use in forensics by delivering enhanced performance and ease of use in an economical platform. The TracER's high-intensity output enables it to perform a non-destructive crime-scene sweep efficiently, recovering fingerprints and other trace evidence solely from inherent fluorescence. And the 532 nm wavelength is ideal for use with fumed samples and fluorescent probes, such as ninhydrin, Coherent said.

The TracER is comparable in size and price to systems that use an alternative light source, but it offers 10 times higher brightness. In addition, TracER includes a fiber-coupled multifunction handpiece, which incorporates power controls (e.g. on/off, output level) as well as optical zoom capabilities to optimize the size and intensity of the speckle-free illumination area.

Lasers have long been known to offer superior evidence recovery capabilities when compared to lamp-based systems. However, the high cost and lack of portability of traditional laser technology have limited lasers to a few well-funded crime labs. TracER uses Coherent's optically pumped semiconductor laser technology to deliver the advantages of laser illumination in a system that is approximately one-third the cost and one-quarter the weight of existing laser-based tools, according to the company.
