TT OPV322 Vertical cavity surface emitting laser in lateral pill package Datasheet

OPV322
Features:
 850 nm VCSEL technology
 High thermal stability
 Low drive current
 High output power
 Narrow beam angle
Description:
The OPV322 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a dome lens pill package. VCSEL offer many
advantages in sensing applications when compared to infrared LEDs. These devices require substantially lower drive
currents to obtain the same amount of output power as LEDs. This feature allows VCSELs to be used in low power
consumption applications such as battery operated equipment.
The dome lens packaging creates a narrow beam angle from the device. Long distance applications may benefit from this
feature as secondary optics may be eliminated, reducing total system cost. The OPV322 is optically and spectrally
compatible with Optek’s standard detector products such as the OP600 series phototransistors, OP300 series
photodarlingtons and the OP900 series photodiodes.
Applications:

Additional laser safety information can be
found on the Optek website. See application
bulletin #221.
Classification is not marked on the device
due to space limitations. See package outline for centerline of optical radiance. Operating devices beyond maximum rating may
result in hazardous radiation exposure.

NOTES:
(1) RMA flux is recommended. Solder dwell time can be increased to 10 seconds when flow soldering.
(2) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 4 mA to 6 mA. Line 2 from 0 mA to 0.5 mA.
(3) Series Resistance is the slope of the Voltage-Current line from 5 to 8 mA.
(4) Slope efficiency, is the slope of the best fit LI line from 5 mA to 8 mA with 0.25mA test intervals.
