The OPV320 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a flat lens pill package. VCSELs
offer many advantages in sensing applications when compared to infrared LEDs. These devices require substan-
tially 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 flat lens packaging allows the device to be used with secondary optics to create custom beam profiles. The
OPV320 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.

bulletin #221.
Classification is not marked on the device
due to space limitations. See package out-
line for centerline of optical radiance. Oper-
ating 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.
