Infrared Emitter

Tue, 10/26/2004 - 11:37am

Agilent introduces a high-speed LED infrared (IR) emitter. The new product, from Agilent's Semiconductor Products Group, uses the company's high-power aluminum gallium arsenide (AlGaAs) LED technology, which has been optimized for high radiant intensity, speed, and low forward voltage. The Agilent HSDL-4261 IR emitter provides manufacturers with a low-cost illumination source suitable for a broad range of applications, from communication devices and IR LANs to consumer products such as optical mice, IR headphones, microphones and keyboards. The HSDL-4261 emitter features 15 ns rise time and 45 ns fall time (10 - 90%), with intensities of up to 180 mW/sr (typical) at ILED=100 mA at a 26° viewing angle. It operates at the 870 nm optical wavelength and is supplied in a 5 mm (T-1 3/4) form-factor package. The Agilent IR emitter is built with iron lead frames that dissipate power efficiently over a wide range of currents. The forward voltage is a low 1.40 volts at 20 mA.
