The C5949 is a compact, high-resolution, light-spot position measurement system using a non-discrete position sensitive detector (PSD) and infrared LED. The system allows you to track the movement of up to seven LEDs (LED target: M1375-16) that are attached to an object and measured in real-time (300Hz). An IR filter and background-light elimination circuit installed in the sensor head allows for accurate measurement. Using the optional M6523 LED Driver, wireless operation between the controller and LED target is possible. Two C5949 systems can be combined to conduct threedimensional measurements.
