Infrared LED
L7560-04
High-speed, high output power LED with
mini-lens
The L7560-04 is a high-speed, high-power LED with a micro-ball lens bonded to the surface of the LED chip having an in-
ternal confinement structure. In addition to the micro-ball lens, the LED chip is sealed with a cap with a mini-lens to make
the output beam even narrower. This allows highly efficient input of the beam into an optical fiber, making the L7560-04
well suited for optical fiber communications.
