The optoNCDT 2300-2DR high precision blue laser displacement sensor is designed for highly dynamic measurements on reflective and shiny targets. Unlike conventional laser sensors, the optoNCDT 2300-2DR uses the directly reflected light of the laser. Due to the blue laser light, the signal on the receiver element is extremely stable, so the sensor can measure with a resolution of nanometers. An extremely small laser spot size enables reliable detection of very small objects.
