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 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 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.

Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
