(3) e e(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 30 cone. the radiant intensity is not necessarily uniform within the measure area. (4) measurement made with 100 m s pulse measured at the trailing edge of the pulse with a duty cycle of 0.1% and an i f = 100 ma. prod uct bul le tin OP235W p r e l i m i n a r y july 2001 gaa las her metic in fra red emit ting di odes type OP235W op tek tech nol ogy, inc. 1215 w. crosby road car roll ton, texas 75006 (972) 323- 2200 fax (972) 323- 2396
