Sensing Chip Uses Raman Spectroscopy to Detect Cocaine in Minutes
A chemical sensing chip, developed for use with surface-enhanced Raman spectroscopy (SERS), has demonstrated the ability to detect the chemical fingerprint of cocaine in biological samples. In the future, the technology could be used to detect the presence of other drugs, including marijuana, and could be integrated into a hand-held, portable device for on-site testing.

Hyperspectral Imaging Fights Food Waste
For food producers and retailers, quality control and assurance still rely on manual, lengthy, destructive processes, such as visual inspections, sensory evaluation, and sample-based testing. Noninvasive, rapid, objective techniques for monitoring food products are essential to improving the sorting and distribution processes. This is where hyperspectral imaging has great promise.

Digital Mini-Chrom Monochromators
Optometrics Corporation
The Digital Mini-Chrom (DMC) is a manually operated monochromator that utilizes a digital counter for wavelength selection. Rotation of the dial causes, via a precision lead screw/ sine bar mechanism, rotation of the diffraction grating which positions the selected wavelength at the exit slit. Request Info Visit Website
