- Flat lens The OPV320 is a Vertical Cavity Surface Emitting Lase r (VCSEL) packaged in a flat lens pill package. VCSELs offer many advantages in sensing applications when comp ared to infrared LEDs. T hese 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. Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.

Solder dwell time can be increased to 10 seconds when flow soldering. (2) Threshold Current is based on the two li ne 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.
