With the rapid development of optoelectronics technology, 850nm infrared LED (IR LED) has become a popular product in the industry. This article will introduce the basic concepts, applications, and market trends of 850nm IR LED in detail.

Basic Concepts of 850nm IR LED

850nm infrared LED is a type of infrared LED with a center wavelength of 850nm. It belongs to the near-infrared spectrum and has excellent transmission characteristics in the atmosphere. Compared with other wavelengths of infrared LEDs, 850nm IR LED has the advantages of strong penetration, long transmission distance, and stable performance. It is widely used in various fields such as security monitoring, communication, and medical equipment.

Working Principle of 850nm IR LED

The working principle of 850nm IR LED is based on the photoelectric effect. When the current passes through the LED chip, the electrons and holes in the semiconductor material are combined, releasing energy in the form of photons. The energy of the photons is determined by the band gap of the semiconductor material. In the case of 850nm IR LED, the semiconductor material is usually gallium arsenide (GaAs), which has a band gap of about 1.42eV, resulting in a center wavelength of 850nm.
