PET/PC Optical Diffuser Films for AOI Vision Inspection

YONGTEK’s AOI light diffuser film is engineered for automated optical inspection (AOI) systems requiring uniform and stable illumination. Designed for both side-lit and direct-lit configurations, the diffuser film evenly diffuses LED light to minimize glare, reduce LED hot spots, and improve camera recognition accuracy. Our led light diffuser films are available in different light transmittance rates and thicknesses to meet the specific needs of various machine vision light sources.
