Qualitätsprüfung in der Glasindustrie

An optical, nondestructive measuring process using laser technology. Presentday requirements applicable to the surface of special types of glass call for a non-destructive measuring technique. With very low contact forces, this cannot be achieved with conventional, tactile measuring systems. Here, the potential of optical measuring systems for non-destructive measuring purposes is presented with reference to two industrial applications, namely the quality testing of display window glass and the ultra-precise measurement of mirrors.
