Top four benefits to using Reflected Ultra-Violet Imaging Systems (RUVIS)

By: Jocelyne Terilli

In the 1970s, Chinese and Japanese forensic scientists were frustrated by not finding all latent fingerprints or contaminating the fingerprints they found via numerous development steps. They sought to create a new technology that would let them find a print without altering or touching it in any way.

Using Shortwave Ultra-Violet Light (254 nanometer), they found that the UV light would reflect off fingerprints. Using a special imager with a quartz lens, it could convert the light to a visible range. In the end, they found that using this technology, an investigator could search for prints using the imager and nothing else. There were no additional steps that could potentially alter or destroy the print.

Over the last 40 plus years, RUVIS has helped crime scene investigators and forensic scientists find more latent prints and evidence. David Alford, a retired FBI Special Agent and Sirchie Instructor identifies the top four benefits of using RUVIS systems during crime scene investigations and forensic laboratory work.

  1. Saving Time. No powders, no dye stains, no additional development processes needed with RUVIS as “you only need to use the Krimesite Imager to look for fingerprints,” says David. Making your life easier to detect & document treated or untreated latent prints.
  2. Preventing Contamination. Because you’re not altering the print to see it, there’s little chance of contamination of the evidence. David adds, “This helps keep the integrity of your evidence while you photograph prints.”
  3. Find Evidence on Difficult Surfaces. RUVIS is ideal for non-porous surfaces that may make it difficult to see a latent print. Glossy magazines with multi-colored backgrounds, aluminum cans, and waxed floors can prove challenging to find a print and identify good detail. “RUVIS helps eliminate the noise and highlights details.”
  4. Find More Evidence. It’s not only latent fingerprints, RUVIS can help you search for tire impressions and footwear impressions. “At a scene, I’ve found many footwear impressions with RUVIS, more than what I thought was there,” says David. With RUVIS, it helps you collect even more evidence. “Lab technicians have reported they find up to 1/3 more prints using RUVIS,” adds David.

With over 20 years of experience as an investigator, David was involved in the investigation of many domestic and international violent crimes and bombings including the Polly Klaas kidnapping and murder, the Unabomber’s cabin, and the 9/11 Pentagon scene. As a Sirchie Instructor, he will be teaching sections of our popular Evidence Collection class in November.  There’s still time to register.
