Compared to sensors that use LED light, Panasonic laser sensors offer many decisive advantages. Due to its very nature, the laser beam ends in a point of light on the objects being sensed that is much smaller than that of LED sensors. This yields markedly higher accuracy, allowing machines to work more precisely and at higher speeds. Moreover, the comparatively "high energy" laser beam exhibits greater illuminance, which in turn improves sensing. In short, this means sensing that is more "precise" and more "reliable". Laser sensors offer a long sensing range and precision that can not be matched with LED based solutions. Panasonic laser amplifiers contain the same high-speed response and built-in features that can be found in the high end fiber optic amplifiers, so you are ensured the highest quality sensing available.
