ASDL-4770
High Performance Side look AlGaAs/GaAs Infrared (940nm) Lamp
Data Sheet
Description
Features
ASDL-4770 is a high performance Infrared emitter that • Side Look Package
utilizes AlGaAs on GaAs LED technology. It is optimized
for high efficiency at emission wavelength of 940nm
and is designed for applications that require high radiant
• 940nm wavelength
• Low Forward Voltage
intensity, low forward voltage at wide viewing angle. • Narrow Viewing Angle
The emitter is encapsulated in Side Look package with
spherical side view lens and is matched to ASDL-6770 for
maximum sensitivity.
• Good Mechanical and Spectral matching to ASDL-6770
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
• Light Barriers
