Particle inspection (a subset of cosmetic surface inspection) detects particles and foreign materials on or within transparent components like clear plastic, film, or glass. These particles may cause material to be unsuitable for a subsequent process in manufacturing, or dangerous for application or consumption. Automated visual inspection systems must be specially calibrated to detect and distinguish between particles and their locations. Understanding whether a particle is on the top or bottom of a surface, or embedded within the surface, allows you 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 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 determine the acceptable severity of a particles or number of particle within the material.

Dust below a smartphone camera lens is detected using specialized lighting to reduce glare from specular glass and increase particle contrast.
