The DL100-7PCBA3 is a dual axis position

sensing diode with sum and difference amplifiers. It

contains internal bias circuitry of 14.3 volts for the

position sensing diode, or the user can externally

apply a bias voltage. The board has a 9 pin

connector for easy hook up.

Outputs are bipolar voltage analogs of the X and Y

position of the light spot centroid, as well as the

total X current and the total Y current. The sum

outputs may be used to externally normalize the X

and Y difference outputs. By normalizing the X and

Y signals, they become independent of fluctuations

in light spot intensity.
