ASDL-4262
High Power T-3/4 (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-13/4 (5mm) package and is suitable for high performance replacements of standard emitters.
