Through the evaluation of polarization characteristics using a 940nm LED, it was discovered that the Asahi Kasei Wire Grid Polarizer Film (WGF) can effectively assess polarization in the NIR spectrum. By incorporating a Bayer colour sensor and NIR sensor in model C3, printing inspection with colour images and tablet inspection with WGF (NIR) is made feasible. This advancement allows for clearer imaging and accurate detection of printing on tablets. #NIR #PolarizationFilter
