850nm LED, also known as the near-infrared (NIR) LED, has gained significant attention in the industry due to its unique properties and applications. This article aims to provide a comprehensive introduction to the 850nm LED market, covering its technology, advantages, applications, and future prospects.

Introduction to 850nm LED Technology

850nm LEDs are a type of semiconductor device that emits light at a wavelength of 850 nanometers, which falls within the near-infrared spectrum. Unlike visible light LEDs, which are commonly used in lighting and displays, 850nm LEDs emit light that is not visible to the human eye. This makes them ideal for applications where invisible light is required, such as in medical, industrial, and communication fields.

The technology behind 850nm LEDs involves the use of gallium arsenide (GaAs) or indium gallium arsenide (InGaAs) as the semiconductor material. These materials have a direct bandgap, which allows for efficient light emission when an electric current is applied. The LED structure typically consists of a p-n junction, with a p-type layer and an n-type layer, which creates a built-in electric field that promotes electron-hole recombination and light emission.
