Flat lens package
The OPV330 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a flat lens lateral package.
VCSELs 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 flat lens packaging allows the device to be used with secondary optics to create custom beam profiles. The
OPV330 is optically and spectrally compatible with Optek’s standard detector products such as the OP550 series
phototransistors, OP530 series photodarlingtons and the OP900 series photodiodes.

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.
