IR Emitter Gets Radiantly Intense

Featuring a unique surface emitter technology and parabolic lens for a narrow ±3º angle of half intensity, the VSLY5850 85-nm infrared (IR) emitter delivers a radiant intensity of 600 mW/sr at a 100 mA drive current. It also packs an optical output power to 55 mW and 10-ns switching times. The device is optimized for IR illumination in CMOS cameras, fire alarm systems, and smoke detectors as well as high modulation frequency applications for long-range data transmission in road cash systems, traffic controls, and license plate flashing. Other features include an operating temperature from -40°C to + 85°C. Pricing ranges from $0.20 to $0.28 each/3,000 to 7,500. VISHAY INTERTECHNOLOGY, INC., Malvern, PA. (619) 336-0860.
