OPV382

Vertical Cavity Surface Emitting Laser in Lateral Package OPV382 • • • • • 850nm VCSEL technology High thermal stability Low drive current High output power Narrow Beam Angle The OPV382 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a dome 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 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 OPV382 is optically and spectrally compatible with Optek’s standard detector products such as the OP500 series phototransistors, OP530 series photodarlingtons and the OP900 series photodiodes.
