With the rapid development of technology, infrared (IR) light-emitting diodes (LEDs) have become increasingly important in various applications. Among them, the 880 nm IR LED stands out due to its unique properties and wide range of uses. This article aims to provide an in-depth introduction to the 880 nm IR LED industry, covering its history, technology, applications, and future prospects.

History and Evolution of IR LED 880 nm

The concept of IR LED dates back to the early 20th century when the first semiconductor diodes were invented. However, it was not until the late 1960s that the first IR LED was developed. Initially, these LEDs were used in simple applications such as remote controls and night vision devices. Over the years, the technology has evolved significantly, and the 880 nm IR LED has emerged as a popular choice due to its longer wavelength and improved performance.

Technology of IR LED 880 nm

IR LED 880 nm operates based on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing it to emit light. The key to achieving 880 nm wavelength lies in the material composition and structure of the LED. Typically, these LEDs are made of materials such as AlGaInAs or InGaAsP, which have the desired bandgap to emit light at 880 nm.

One of the key advantages of the 880 nm IR LED is its high efficiency. This is due to the fact that the wavelength is close to the peak of the responsivity of the human eye, making it more efficient in converting electrical energy into light. Additionally, the longer wavelength of the 880 nm IR LED allows for better penetration through certain materials, making it suitable for applications such as thermal imaging and remote sensing.
