Block Engineering Laser Scan Analyzer
Description
LaserScan™ detects and measures substances on surfaces from a standoff
distance of 6 inches to 2 feet or can be customized to do longer standoff.
LaserScan can identify bulk materials and detect sub-micron films based on
their absorption characteristics. It can also analyze vapors or liquids. An
alternate version of the device is designed to interface to common FTIR
accessories, including liquid and gas cells
Comparison to FTIR & Raman
LaserScan puts more energy at a specific wavelength on the sample than
a Fourier Transform Infrared (FTIR) . This creates the potential
for higher sensitivity and higher power density measurements especially from
diffuse and highly absorbing materials and substrates. Other advantages
over FTIR include , fast analysis, and the ability to
work at a distance either through free space or a fiber. FTIRs cannot offer, making it difficult to quickly scan surfaces and avoid. Whereas an FTIR takes minutes to analyze ,
the LaserScan takes seconds
