BPD-8L Datasheet, PDF (1/3 Pages) Advanced Photonix, Inc. – BEAM POSITION DETECTOR

BEAM POSITION DETECTOR
BPD-8L
OUTPUT SIGNALS
• Sum of all four quadrants.
• Difference between lower
and upper halves.
• 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.
