SAN DIMAS, Calif., March 11, 2011 — Craic Technologies Inc. has collaborated with Laboratory Imaging sro to introduce the rIQ (refractive index quantification) system for analyzing glass trace evidence.

It combines sophisticated image analysis software, an advanced optical design and electronics to enable criminalists in modern forensic laboratories to measure and quantify the refractive index of multiple glass fragments simultaneously, quickly and accurately. It monitors the change in refractive index of calibrated oils as they are heated and cooled.

It is offered in a turnkey stand-alone configuration, as part of a microspectrophotometer that includes color analysis of glass, or as part of an upgrade package for older units already in the field. The stand-alone package consists of a phase contrast microscope, a high-resolution digital camera, the optical interface, a thermal stage, controlling electronics, and software designed to be intuitive that incorporates powerful algorithms. The add-on package can be integrated with many Craic microspectrophotometer models, both past and present, to allow them to measure the color, absorbance microspectra, fluorescence microspectra and refractive index.

The system also performs environmental monitoring, including ambient temperature and control, as well as databasing and statistical analysis. It enables forensic scientists to measure and compare the refractive index of the smallest fragments of glass. When combined with Craic’s microscope spectrophotometers and microcolorimeters, the transmission, fluorescence and color spectral characteristics of glass evidence can also be determined quickly.

The automated system uses the thermal-optical immersion method, as defined by the standard ASTM E1967-98, to measure the refractive index of microscopic glass fragments. Statistical analysis methods can be applied, but the instrument is also designed to be user friendly, with a short learning curve.
