*1: In the range 75% from the center of the photosensitive area to the edge
*2: This indicates the upper limit of the photocurrent linearity over the entire incident light quantity and is defined as the photocurrent
at a point where the linearity deviates by 10%.
*3: Time required for output change from 10 to 90% of the steady output value when stepped function light is input to the PSD

Saturation photocurrent vs. interelectrode resistance Definition of position detection error

(Typ. Ta=25 °C) When the electrical center of a PSD is assumed to be the
1 mA
position of incident light where light current I1 equals I2, position
detection error at each incident position can be defined by the
VR=5 V
following equation.
VR=2 V I2 - I1 L
Saturation photocurrent

Position detection error (μm) = Incident position - ×

100 μA I1 + I22
The electrical center is viewed as 0, I1 as (+), and I2 as (-).
