The MIE-324H4 is a GaAlAs infrared LED having a
Unit : mm (inches )
peak wavelength at 850nm. It features ultra-high power,
high response speed and molded package with higher
φ 3.50±0.25
φ 3.10±0.20
radiant intensity. In addition to improving the S/N ratio
in applied optical systems, the MIE-324H4 has greatly
improved long-distance characteristics as well as sign-
