Plastic Infrared Emitting Diode

OP290 Series

Notes:

1. Measurement is taken at the end of a single 100 µs pulse. Heating due to increased pulse rate or pulse width will cause a decrease

in reading.

2. Measurement of the average apertured radiant energy incident upon a sensing area 0.250” (6.35 mm) in diameter perpendicular to

and centered on the mechanical axis of the lens and the specified distance from the end of the device. On all models in this series,

3. Measurement is taken at the end of a single 10 ms pulse. Heating due to increased pulse rate or pulse width will cause a decrease in

reading.
