- Narrow Beam Angle The OPV322 is a Vertical Cavity Surface Emitting Las er (VCSEL) packaged in a dome lens pill package. VCSEL offer many advantages in sensing applications when compar ed to infrared LEDs. These devices require substan- tially lower drive currents to obtain the same amount of out put power as LEDs. This feat ure 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.
