retroreflektor with a color filter for optical sensors and reflexionslichtschranken

摘要

retroreflektor with a retroflektierenden structure (1.3, 2.6, 4.8, 5.1, 6.4, 7.4), in front of a lichteintrittsfläche and at its rear to a reflection of the retroflexion lichteintrittsfläche incidental light iswith the retroflektierende structure (1.3, 2.6, 4.8, 5.1, 6.3, 7.4) to the back of a layer of metal (5.5, 6.3, 7.3), in which the beam path before the lichteintrittsfläche the retroflektierenden structure (1.3, 2.6, 4.8, 5.1, 6.3, 7.4) verzögerungsschicht in the form of a 1 / 4 cameras (6.6, 7.(6) is arranged, and a color filter (2.6 4.6, 5.4, 6.2, 7.4) from a translucent material in a predetermined color of light of predetermined wavelength selective pedal right to the floor.the beam of incident light to the reflection is arranged.
