New Mexico State University Researchers Receive Funding to Use
Raydiance USP Laser Platform to Detect Counterfeiting of Precious
Gemstones
USP Laser’s Precision Enables
Spectroscopic Analysis without Gem Devaluation
LAS CRUCES, N.M. (Business Wire EON/PRWEB ) February 14, 2008 --
Raydiance, Inc., developer of the world’s
first compact, cost-effective and fully software-controlled UltraShort
Pulse (USP) laser system, today announced that it is working with a
leading geologist at New Mexico State
University (NMSU) who has received funding for laser-induced
breakdown spectroscopy (LIBS) of rock and mineral compositions, a
process by which researchers are able to analyze small parts of a
mineral in a way that is essentially non-destructive.
As part of this initiative, the precision and power of the Raydiance USP
platform will allow researchers to differentiate fake gemstones from
real gemstones, as well as uniquely identify individual gemstones with
certainty, without causing damage to the stones. Until now, other lasers
that have been effective at this technique have not been small,
portable, precise or inexpensive enough to be practical for commercial
use. They have also typically caused collateral damage to the material
being examined.
Nancy
McMillan, PhD, professor and academic head of the Department of
Geological Sciences at NMSU and principal investigator of the gemstone
project, said, “Lasers have been used in the
past to determine the type, origin and quality of gemstones. However,
until we saw Raydiance’s technology in action,
we had never seen a laser that does not cause damage to the stone,
lowering its value. Looking ahead, we expect the Raydiance USP laser
platform to be an invaluable tool for appraisers and insurers across the
industry.”
McMillan’s project aims to illustrate how
Raydiance lasers can detect gemstones that were treated to look like
real stones, such as chemically-coated diamonds, rubies injected with
leaded glass to superficially remove flaws, and sapphires that have been
diffused with the element beryllium to produce a brilliant orange color.
The research will also test the laser’s
capability to identify minerals that are being illegally sold as more
expensive ones, such as synthetic forsterite sold as tanzanite.
Today, gemstone evaluation most-commonly consists of either subjective
visible inspection, examining a stone’s
refractive index, or inspection with a microscope.
USP lasers are extremely brief light pulses of unprecedented power that,
unlike continuous wave lasers, instantly vaporize any material without
heat or residual damage at very precise scales, down to the micron
level. Until now, most USP systems have been extremely expensive, very
large and usable only by photonics experts.
Raydiance President Scott Davison said, “We
are thrilled to partner with NMSU on these exciting, groundbreaking
projects. As a leader in research and development, NMSU is exactly the
type of research hub we look to partner with to develop innovative
commercial applications that will not only disrupt the marketplace, but
also foster knowledge-based job growth for the state of New Mexico.”
Dr. McMillan’s work is one of six research
projects on the Raydiance USP laser platform currently underway at NMSU.
Each multi-disciplinary team is developing novel applications based on
the unique properties of Raydiance lasers to identify promising,
high-growth ideas and projects that can be commercialized within New
Mexico. Other projects include spectroscopic techniques for sensitive
detection and identification of chemical species or microorganisms and
live imaging of neural and sensory tissue for biomedical applications.
