LaserScan™: Handheld Quantum Cascade Laser Spectrometer
Description
LaserScan, our widely tunable mid-IR QCL spectrometer, detects and measures substances on surfaces from a standoff distance of 6 inches to 2 feet. LaserScan identifies bulk materials and detects sub-micron films based on their mid-IR absorption characteristics. Key applications include detection of explosive materials, traditional and nontraditional chemical agents, and toxic industrial chemicals. It can also analyze gases and liquids. An alternate version of the device is designed to interface with common FTIR accessories, including liquid and gas cells, and reflectance accessories.
