  SUM AND DIFFERENCE AMPLIFIER MODULES

  SILICON POSITION SENSING  DETECTORS

QD7-0-SD or 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 analogues of the relative intensity difference of the light sensed by opposing pairs of the photodiode quadrant elements. In addition the amplified sum of all 4 quadrant elements is provided as the sum signal. This makes the QD7-0-SD or QD50-0-SD ideal for both light beam nulling and position applications. Very precise light beam alignments are possible, and the circuit can also be used for target acquisition and alignment.

Please note that the QD50-0 and QD7-0 model numbers refer to the stand alone quadrant photodiodes. To order to complete Sum and Difference modules please use the following models number: QD50-0-SD and QD7-0-SD for the 50mm2 and 7mm2 version respectively.
