High Power Output IREDs Deliver Narrow Beam April 2004 Issue Published Date: April 08, 2004
Two new IREDs have been developed for applications requiring uniform output radiation patterns. Designed with custom plastic lenses, the TO-46, 850 nm IREDs, models CLE331P and CLE335P, are claimed to have a narrower beam angle, better collimation, and higher performance at a lower cost than metal can devices. The CLE331P contains an AlGaAs point source die with a 50-micron diameter junction. At I&subF; = 100 mA, typical power output is 3.0 mW, typical rise and fall time is 5 ns, maximum VF is 2.2V and emission angle at the half power points is ±2°. The CLE335P contains an AlGaAs DDH die with 50% greater power output than standard AlGaAs emitters. At I&subF; = 100 mA, typical power output is 25 mW, typical rise and fall time is 30 ns, maximum VF is 1.9V and emission angle at the half power points is ±4°. Both devices can be operated at up to 3A when pulsed at 10 µs, 100 pps. Maximum operating temperature is 100°C. Pricing ranges from $1.87 to $2.48 each/1,000. CLAIREX TECHNOLOGIES INC., Plano, TX.
