“Compared with other infrared technologies, VCSEL offer better beam quality, excellent focusing and a very small footprint”, said Bianka Schnabel, Marketing Manager for the Emitter Laser Sensor segment at Osram Opto Semiconductors. “Customers can now choose the best solution for their specific application from our extended infrared portfolio – whether it’s IRED, laser or VCSEL.”
With a wavelength of 940 nm, PLPVQ 940A offers a maximum efficiency of 27 percent and an output of 300 mW. Two bond wires supply the laser diode uniformly and rapidly with energy. The angle within which the VCSEL provides illumination is 65° x 78°. Its package is extremely small, measuring just 1.90 mm x 2.20 mm x 0.85 mm.
Possible applications for VCSEL products are many and varied. In addition facial recognition, the components are suitable for applications in robotics, drones, augmented reality and virtual reality.
