HSDL-4260
High-Power T-1¾ (5mm) AlGaAs Infrared (875nm) Lamp
Datasheet
Description
The HSDL-4260 High Power Infrared emitter
was designed for applications that require high
power, low forward voltage and high speed. It
utilizes Aluminum Galium Arsenide (AlGaAs)
LED technology and is optimized for speed and
efficiency at emission wavelengths of 875nm.
The material used produces high radiant
efficiency over a wide range of currents. The
emitter is packaged in clear T-1¾ (5mm)
package.
