Infrared light, also known as infrared radiation, is a type of electromagnetic radiation with longer wavelengths than visible light. It has been widely used in various industries due to its unique properties and applications. This article will provide an in-depth introduction to the infrared light industry, covering its history, technology, applications, and future prospects.

History of Infrared Light

The concept of infrared light was first proposed by British physicist Willian Herschel in 1800. Through his experiment, Herschel discovered that there was a type of invisible light beyond the red light spectrum, which was later named infrared light. Since then, infrared technology has developed rapidly, and its applications have become increasingly extensive.

Technology of Infrared Light

Infrared light technology mainly includes the following aspects:

• Spectroscopy: Infrared spectroscopy is a technique that uses infrared light to analyze the chemical composition and molecular structure of substances. It has been widely used in the fields of material science, chemistry, and environmental protection.
• Thermography: Infrared thermography is a technique that uses infrared light to measure the temperature distribution of objects. It is widely used in industrial inspection, building energy conservation, and medical diagnosis.
• Infrared imaging: Infrared imaging is a technique that uses infrared light to form images. It is widely used in military, security, and aerospace fields.
• Infrared communication: Infrared communication is a technique that uses infrared light for wireless communication. It is commonly used in remote control devices, such as TV remote controls and computer mice.
