ASDL-4772
High Performance Side look AlGaAs/GaAs Infrared (940nm) Lamp
Data Sheet
Description
Features
ASDL-4772 is a high performance Infrared emitter that is • Side Look Package
optimized for high efficiency at emission wavelength of
940nm. It is designed for applications that require small
outline dimensions with high radiant intensity and low
• 940nm wavelength
• Narrow Viewing Angle
forward voltage at wide viewing angle. The emitter is en- • Good Mechanical and Spectral matching to ASDL-6771
capsulated in Side Look package and is matched to ASDL-
6771 for maximum sensitivity.
Infrared Phototransistor Detector
• Lead Free and ROHS Compliant
• Available in Tape & Reel
Applications
• Industrial Infrared Monitoring Applications
• Consumer Electronics (Optical Mouse)
• Infrared Source for Optical Counters and Card Readers
• Photo-Interrupters
• On-Off Switch / Beam Interruption
• Positioning Sensing
