Hyperspectral Line Imager

HORIBA has developed a compact industrial spectrometer platform that is factory-configurable for use in a hyperspectral imaging system. In hyperspectral imaging applications, this system can be used as a line-scanning instrument (push-broom) that collects full spectral data simultaneously across the input slit height.

Dimensions: 2 x 3.5 x 2 inches (51 x 90 x 51 mm)
Weight: 1.5 lbs (680 g)
