With the rapid development of technology, the 850nm IR LED (Infrared Light Emitting Diode) has emerged as a crucial component in various applications, ranging from consumer electronics to industrial automation. This article aims to provide an in-depth introduction to the 850nm IR LED industry, exploring its technology, applications, market trends, and future prospects.

Introduction to 850nm IR LED

The 850nm IR LED is a type of infrared light emitting diode that emits light at a wavelength of 850 nanometers. Unlike visible light, infrared light is not visible to the human eye, making it ideal for applications where stealth or concealed operation is required. The 850nm IR LED is widely used due to its high efficiency, long lifespan, and stable performance.

Technology of 850nm IR LED

The 850nm IR LED is typically made of Gallium Arsenide (GaAs) or Aluminum Gallium Arsenide (AlGaAs) materials. These materials are chosen for their ability to emit infrared light at the desired wavelength. The manufacturing process involves epitaxial growth, where a thin layer of the semiconductor material is deposited on a substrate to form the LED structure. The structure is then patterned and mounted on a lead frame, ready for packaging.

During the epitaxial growth process, the composition and thickness of the layers are carefully controlled to achieve the desired emission characteristics. The key parameters include the bandgap energy, which determines the wavelength of the emitted light, and the doping concentration, which affects the electrical properties of the LED.
