Optical response of the IF-D92 extends from 400 to 1100 nm, making it compatible with a wide range of visible and near-infrared LEDs and laser diode sources. This includes 650 nm visible red LEDs used for optimum transmission in PMMA plastic optic fiber. The detector package features an internal micro-lens and a precision-molded PBT housing to ensure efficient optical coupling into standard 1000 µm core plastic fiber cable.

Cut off the ends of the optical fiber with a singleedge razor blade or sharp knife. Try to obtain a precise 90-degree angle (square). 2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal micro-lens. 3. Screw the connector locking nut down to a snug fit, locking the fiber in place. mA FIGURE 2. Rise and fall times of phototransistor. PACKAGE IDENTIFICATION: Black housing w/ White dot • PIN 1.
