description

The CLE331 is an advanced, high

efficiency, high speed, point source,

AlGaAs infrared-emitting diode

intended for use in applications

requiring a uniform output radiation

pattern. The point source die junction

is 0.002" in diameter, and the dual

aspheric lens provides a highly

collimated radiation source. Beam

pattern is very uniform without the

bond wire shadow effect of standard

infrared emitting diodes.
