(3) Ee(APT) 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 30cone. The radiant intensity is not necessarily uniform within the measure area. (4) Measurement made with 100s pulse measured at the trailing edge of the pulse with a duty cycle of 0.1% and an I F = 100 mA. 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. Optek Technology, Inc. 1215 W.
