Infrared LED

L7558 series

High-speed, high-power infrared LED for free

space optics

The L7558 series LEDs were developed for free space optical communications such as image data signal transmission, and

operate at high speeds of 50 MHz.

The L7558 delivers a high output of 14 mW and is used in combination with a light projection lens. The L7558-01 is sealed in

a metal package capped with a glass lens that produces an angle of view of ±7° (full angle at half maximum).

Both types employ a metal stem package that gives higher reliability than plastic package devices.
