ASDL-4671
High Performance T- (3mm) AlGaAs/GaAs Infrared (940nm) Lamp
Data Sheet
Description
ASDL-4671 is a high performance Infrared emitter that
utilizes AlGaAs on GaAs LED technology. It is optimized
for high efficiency at emission wavelength of 940nm
and is designed for application that requires high radiant
intensity, low forward voltage at narrow viewing angle.
The emitter is encapsulated in T1 (3mm) package and is
both mechanically and spectrally matched to ASDL-6620
Infrared phototransistor detector.
