Carrollton, Tex. TT electronics OPTEK Technology recently introduced a low drive current vertical cavity surface emitting laser (VCSEL) for long distance sensing applications. Designated the OPV232, the 850 nm VCSEL is available in a low-cost plastic T-1 package and features a dome lens that creates a narrow 3-degree beam angle, eliminating the need for secondary optics.
The company said VCSEL technology offers many advantages in sensing applications in comparison to infrared LEDs. The OPV232 VCSEL requires substantially lower drive currents to obtain the same amount of output power as LEDs, enabling the device to be used in low power consumption applications such as battery-operated equipment.
The OPV232 features excellent electrical characteristics with a maximum forward peak current of 30 mA and reverse voltage of 5 V. The maximum operating temperature range is -40°C to 85°C. The T-1 package offers a low profile height of 3 mm.
The OPV232 VCSEL is suitable for position sensing applications such as photoelectric sensors, optical encoders, light curtains, office equipment and industrial systems. The device is optically and spectrally compatible with OPTEK's standard detector products such as phototransistors, photodarlingtons and photodiodes.
Typical pricing for the OPV232 VCSEL is $5.06 each in quantities of 1,000. Delivery is from stock to eight weeks.
