Introduction to Infrared 850nm LEDs

Background

Infrared 850nm LEDs, also known as 850nm infrared LEDs, are a type of semiconductor device that emits infrared light at a wavelength of 850 nanometers. These LEDs are widely used in various applications, such as remote controls, optical communication, and security systems.
