L7560

High-speed, high output power LED with mini-lens

L7560 is a high-speed, high-power LED with a micro-ball lens bonded to the surface of the LED chip having an internal confined structure. The
package is sealed by a metal cap with a mini-lens, making the output beam even narrower. This allows highly efficient input of the beam into an
optical fiber, making L7560 well suited for optical fiber communications.
