OPV302 Features:  850nm VCSEL technology  High thermal stability  Low drive current  High output power  Narrow beam angle Description: The OPV302 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a dome lens TO-46 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 OPV302 is optically and spectrally compatible with Optek’s standard detector products such as the OP800 series phototransistors, OP830 series photodarlingtons and the OP910 photodiode. Applications:  Non-contact position sensing  Photoelectric sensors  Optical encoders  Light curtains General Note TT Electronics | Optek Technology, Inc.
