*9: The position (mm) of light spot from the center is twice the output voltage (V) for the S1881.
If the incident light spot is not sufficiently focused on the PSD, i.e., the light spot diameter is large, and falls upon near the edge
of the active area, part of the light spot may go outside the active area, thus degrading position accuracy.
The output voltage amplitude values listed above are measured when the light spot diameter is made as small as possible within
the range in which adequate intensity is maintained.
