Please note that the OBP series position sensors are being phased out by the end of 2017.

The OBP-A-4L Optical Position Sensing Detector is designed to measure laser beam displacement at rates of up to 60 kHz with sub-micron spatial resolution. The power range is 10 μW to 2.5 mW. The 0.158 inch (4 mm) square detector head comes with an ambient light shield and can be fitted with up to three, stackable filters (ordered separately). The Position Sensing Detector (PSD) head with +/- 25 μm position accuracy connects to the electronics pack via a 9-pin female D-sub connector. This analog version include a second 9-pin male D-sub connector for interfacing the input and output signals, including power input and analog output signals to monitor power and displacement signals. After connecting the ±18 VDC power supply (included) at the input, the user simply plugs the output signals into a DVM or oscilloscope to monitor and record position and laser beam power.
