OPV380 Features:  850 nm VCSEL technology  High thermal stability  Low drive current  High output power  Narrow beam angle Description: The OPV380 is a Vertical Cavity Surface Emitting Laser (VCSEL) packaged in a flat 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 flat lens packaging allows the device to be used with secondary optics to create custom beam profiles. The OPV380 is optically and spectrally compatible with Optek’s standard detector products such as the OP550 series phototransistors, OP530 series photodarlingtons and the OP900 series photodiodes. Applications:  Non-contact position sensing  Photoelectric sensors Emission  Optical encoders Surface  Light curtains VCSEL 1 2 Additional laser safety information can be found on the Optek website. See application bulletin #221. Classification is not marked on the device due to space limitations. See package out- Pb line for centerline of optical radiance. Oper- ating devices beyond maximum rating may result in hazardous radiation exposure. RoHS General Note TT Electronics | Optek Technology, Inc.
