Infrared LEDs 850, also known as 850nm infrared LEDs, are a type of light-emitting diode that emits infrared radiation at a wavelength of 850 nanometers. This specific wavelength falls within the near-infrared spectrum, making it a popular choice for various applications, including communication, sensing, and imaging. This article provides an in-depth introduction to the industry of infrared LEDs 850, exploring their characteristics, applications, market trends, and future prospects.

Introduction to Infrared LEDs 850

Infrared LEDs 850 are semiconductor devices that emit light in the near-infrared spectrum. They are made up of a p-n junction, where the p-type material has an excess of positively charged carriers (holes) and the n-type material has an excess of negatively charged carriers (electrons). When an electric current is applied to the diode, the electrons and holes recombine, releasing energy in the form of photons. The wavelength of the emitted light depends on the composition and structure of the semiconductor material. The 850nm wavelength is particularly attractive for several reasons. Firstly, it is within the transmission window of many materials, which means it can pass through them without significant absorption or scattering. This makes it ideal for optical communication and sensing applications. Secondly, it is less susceptible to ambient light interference, which is a common issue with shorter infrared wavelengths. Lastly, it is widely available and relatively inexpensive to produce.
