is a measurement of the average radiant intensity emitted by the IRED within a cone
formed from the IRED chip to an aperture. The aperture of diameter 0.250” is located a
distance of 0.466”from the flange (measurement plane) to the aperture plane (parallel to the
measurement plane) along the optical and mechanical axis. The cone formed is a 30°cone.
The radiant intensity is not necessarily uniform within the measure area.

cycle of 0.1% and an I

Description
The OP235W device is an 850 nm
gallium aluminum arsenide infrared
emitting diode mounted in a hermetically
sealed package. The broad irradiance
pattern provides relatively even
ilumination over a large area.
