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.
