The MIE-554H4 is a GaAlAs infrared LED having a
peak wavelength as 850nm. It features ultra-high power,
high response speed and molded package with higher
radiant intensity. In addition to improving the S/N ratio
in applied optical systems, the MIE-554H4 has greatly
improved long-distance characteristics as well as sign­ificantly increased its range of applicability.
