Technical Article: Short-wave IR Offers Unique Remote Sensing Solutions

The shortwave infrared (SWIR) wavelength band is rich in potential for solving imaging challenges in measurement, inspection, and process-monitoring tasks. Spectral signatures in the SWIR can reveal the presence of contaminants or moisture in agricultural products. Hot-furnace processes and walls can be inspected through ordinary safety glass enclosures or with off-the-shelf glass lenses or optics. Glass manufacturers can image in the SWIR at high speed, monitoring the cooling process to identify costly defects inside bottles before waste costs balloon.
