Particles and foreign materials on or within transparent components like clear plastic, film, or glass may cause material to be unsuitable for a subsequent process in manufacturing. Automated visual inspection systems must be specially calibrated to detect and distinguish between particles and pinpoint their locations. Understanding whether a particle is on the top or bottom of a surface, or embedded within the surface, allows manufacturers to adjust operational processes to determine if an inspected material can move on to the next phase of production, if cleaning is required, or if the material must be rejected as scrap.
Radiant’s automated visual inspection solutions employ our ProMetric® Imaging Photometers and Colorimeters with extremely high-resolution, high-dynamic-range image sensors to detect defects in transparent materials under unpredictable lighting conditions. Minute contrast variations within an imaged area allow our cameras to assess the presence and location of particles and apply defined tolerances to characterize the severity of a particle, or the number of particles within the material, and their locations.
