Cross light inspection for detecting surface defects
Surface inspection has been greatly enhanced with the latest developments in LED technology utilized in stroboscopic inspection. The ability to precisely control flash duration time of LEDs now enables inspectors to have sharper and crisper images of the product surface allowing them to detect finer anomalies.
This control over light timing also makes it possible to deploy the simultaneous use of bright field and dark field lighting such that surface imperfections are dramatically enhanced, making it easier for operators to see both common defects in surface quality as well as extremely subtle defects on coated and reflective surfaces.
