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 conï¬ned
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 efï¬cient input of the beam into an optical ï¬ber, making the L11368 well suited for optical ï¬ber
communications.
