850nm LED, also known as infrared LED, is a type of light-emitting diode that emits light at a wavelength of 850 nanometers. This wavelength falls within the infrared spectrum, making it invisible to the human eye. In recent years, 850nm LED technology has gained significant attention in various industries due to its unique properties and applications. This article will provide an in-depth introduction to the 850nm LED industry, covering its history, technology, applications, and future prospects.

History of 850nm LED

The development of 850nm LED technology dates back to the 1960s when the first LED was invented. However, it was not until the late 1990s that 850nm LED technology began to attract attention. Initially, 850nm LED was primarily used in optical communication systems, where it played a crucial role in transmitting data over long distances. As technology advanced, the applications of 850nm LED expanded to other fields, such as consumer electronics, medical devices, and automotive industry.

Technology of 850nm LED

850nm LED is based on the same semiconductor technology as other types of LEDs. The key difference lies in the material composition and the structure of the LED chip. To achieve the desired infrared emission, the semiconductor material used in 850nm LED is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows them to emit light at a specific wavelength.

The structure of an 850nm LED chip typically consists of a p-n junction, where electrons and holes recombine to produce light. To enhance the light output and efficiency, the chip is encapsulated in a clear or transparent material, such as sapphire or silicon dioxide. The encapsulation also helps to protect the chip from external factors, such as moisture and dust.
