Qd7-0-sd/qd50-0-sd Position Sensing Detectors
OSI Optoelectronics’ position sensing detectors are ideal for light beam nulling and position applications OSI Optoelectronics’ QD7-0-SD and QD50-0-SD are quadrant photodiode arrays with associated circuitry to provide two difference signals and a sum signal. The two difference signals are voltage analogs of the relative intensity difference of the light sensed by opposing pairs of the photodiode quadrant elements. …
