Sum of all four quadrants.
鈥?Difference between lower
and upper halves.
鈥?Difference between left and
right halves.
DESCRIPTION
The
BPD-8L
is designed for precise light beam
position detection. The
BPD-8L
provides accurate
measurement of small changes in the position of a
light beam. Its large quad cell design
accommodates both high resolution and larger area
light detection.
