Infrared LED L11368 High output power LED with mini-lens The L11368 is a high-power LED with a microball lens bonded to the surface of the LED chip having an internal confined structure. In addition to the microball lens, the LED chip is sealed with a cap with mini-lens to make the output beam even narrower. This allows highly efficient input of the beam into an optical fiber, making the L11368 well suited for optical fiber communications. Features Applications High radiant output power: 65 μW typ. (IF=50 mA, GI 50) Optical fiber communication Cutoff frequency: 50 MHz typ.
