Infrared diodes are semiconductor devices that emit infrared radiation when an electric current passes through them. They are widely used in various applications, such as remote controls, optical communication, and thermal imaging. This article will provide an in-depth introduction to the infrared diode industry, covering its history, types, applications, and future trends.

History of Infrared Diodes

The concept of infrared diodes dates back to the early 20th century. In 1900, a German physicist named Heinrich Hertz discovered that certain materials emit infrared radiation when they are excited by an electric current. This discovery laid the foundation for the development of infrared diodes. In the 1950s, the first practical infrared diodes were developed, and they have since become an essential component in various industries.

Types of Infrared Diodes

Infrared diodes can be categorized into several types based on their emission spectrum and application. The most common types include: 1. Near-Infrared (NIR) Diodes: These diodes emit infrared radiation in the range of 700 to 1500 nm. They are widely used in optical communication, remote controls, and barcode readers. 2. Mid-Infrared (MIR) Diodes: These diodes emit infrared radiation in the range of 1500 to 3000 nm. They are used in thermal imaging, gas sensing, and scientific research. 3. Far-Infrared (FIR) Diodes: These diodes emit infrared radiation in the range of 3000 to 10000 nm. They are used in remote sensing, thermal imaging, and night vision devices.
