ASDL-4262
High Power T-¾ (5mm) AlGaAs/GaAs Infrared (940nm) Lamp
Data Sheet
Description
ASDL-4262 is a high power 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 wide viewing angle. The
emitter is encapsulated in T-1¾ (5mm) package and is
suitable for high performance replacements of standard
emitters.
