ASDL-4770
High Performance Side look AlGaAs/GaAs Infrared (940nm) Lamp
Data Sheet
Description
ASDL-4770 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 applications that require high radiant
intensity, low forward voltage at wide viewing angle.
The emitter is encapsulated in Side Look package with
spherical side view lens and is matched to ASDL-6770 for
maximum sensitivity.
