Until now, it has been difficult to detect subtle changes in luster on surfaces in commercial and industrial applications. Thanks to Omron Electronics' new E3X-NL photoelectric fiber-optic sensor, the necessary level of discrimination among surface backgrounds, can be achieved using the proprietary free-angle optics (FAO) technology. Omron's polarized light multilayer film technology, FAO, uses a polarized beam splitter made by layering different types of dielectric films on glass. The splitter divides the light that is reflected from the object and transmits only the required component of light to the appropriate receivers.
