Infrared emission, also known as thermal radiation, refers to the electromagnetic radiation emitted by objects at temperatures above absolute zero. This form of radiation is invisible to the human eye but can be detected and utilized in various applications. The field of infrared emission has seen significant advancements in recent years, making it an essential component in numerous industries. This article aims to provide an overview of the infrared emission industry, covering its history, applications, technology, and future prospects.

History of Infrared Emission

The concept of infrared radiation was first discovered by the English physicist William Herschel in 1800. He observed that as the spectrum of sunlight was passed through a prism, there was a region beyond the red end of the visible spectrum that caused a rise in temperature. This region was later named the infrared spectrum. Over the years, the study of infrared emission has led to the development of various technologies, such as infrared cameras, thermal imaging, and remote sensing.
