OPV322 Features: 850 nm VCSEL technology High thermal stability Low drive current High output power Narrow beam angle Description: 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 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 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. Applications: Non-contact position sensing Photoelectric sensors Optical encoders Light curtains 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 outline for centerline of optical radiance. Operating devices beyond maximum rating may result in hazardous radiation exposure.
