While standard monochrome and colour cameras record intensity and wavelength, the Linea ML is available as a polarization camera that captures intensities of multiple polarization states. This renders polarization imaging much more sensitive. It enables acquisition of contrast rich images to detect nonvisible properties such as birefringence, stress, film thickness, and surface roughness. Therefore it's particularly suited for objects that are difficult to distinguish otherwise. Costly and complex hardware solutions can be avoided by using a polarization camera as part of a conventional imaging setup. The integration of polarization imaging allows the improvement of the overall production reliability and quality of customers.
