LED Infrared LED 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. Features Applications l High-speed response: 100 MHz Typ.
