Vertical Cavity Surface Emitting Laser in T-1 Package OPV330 • • • • • 850nm VCSEL technology High thermal stability Low drive current High output power Flat lens package The OPV330 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 OPV330 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. Emission Surface Applications • • • • Non-contact position sensing Photoelectric sensors Optical encoders Light curtains VCSEL 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. 1 2 Pb RoHS Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
