L7558 series
High-speed, high-power infrared LED for spatial light transmission
L7558 series infrared LEDs were developed for spatial light transmission of high-density information such as image data signals, and operate at
high speeds of 50 MHz.
L7558 delivers high output of 14 mW and is used in combination with a light projection lens that matches the application. L7558-01 is sealed in a
metal package capped with a glass lens that ensures narrow directivity of ±7˚(full angle at half maximum). Metal stem package gives L7558 and
L7558-01 higher reliability than plastic package devices.
