Optical Proximity Detector 905nm

Optical proximity detector.
905nm, eye safe, laser range fined

Manufacturer part number: OPD-905-20-1000

OPD is high measurement rate single-pulse laser range finder. The OPD generates 10ns optical pulses and measures time between emitting a pulse and detection of the reflected signal. Short rise time and wide receiver’s bandwidth allow getting accuracy of 5-10 cm. The built-in range detection algorithm generates trigger signal when the measured range drops below predefined threshold.

Product is field-tested , military grade  / rugged. Used for military / defense applications.
