Introduction

Infrared LEDs, specifically those with a wavelength of 850nm, have become increasingly popular in various industries due to their unique properties and applications. This article aims to provide an in-depth introduction to infrared LEDs 850nm, covering their working principles, advantages, applications, and future trends.

What are Infrared LEDs 850nm?

Infrared LEDs, also known as infrared diodes, are semiconductor devices that emit infrared light. The term "850nm" refers to the specific wavelength of the infrared light they emit. Infrared LEDs with a 850nm wavelength have a longer wavelength compared to other infrared LEDs, which makes them suitable for certain applications. The working principle of infrared LEDs involves the injection of electrons and holes into a semiconductor material, typically gallium arsenide (GaAs). When these electrons and holes recombine, they release energy in the form of photons, which are emitted as infrared light.
