Unity Opto Technology MIE-824H2 Datasheet

GaAlAs T-1 3/4 PACKAGE

INFRARED EMITTING DIODE

MIE-824H2

Description

The MIE-824H2 is a GaAlAs infrared LED having a
peak wavelength at 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-824H2 has greatly
improved long-distance characteristics as well as sign­ificantly increased its range of applicability .
