Introduction to Infrared Light nm

Infrared Light nm: A Brief Overview

Infrared light, often referred to as infrared radiation, is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of terahertz radiation. The term "nm" stands for nanometers, which is a unit of length equal to one billionth of a meter. In the context of infrared light, nm refers to the specific wavelength range of this type of radiation. This article aims to provide an in-depth introduction to infrared light nm, its applications, and its significance in various industries.

Wavelength Range of Infrared Light nm

The infrared light nm range spans from approximately 700 nanometers (nm) to 1 millimeter (mm). Within this range, infrared light can be further divided into three sub-ranges: near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). Each sub-range has unique properties and applications. - Near-infrared light (NIR): This range spans from 700 nm to 1,400 nm. NIR is commonly used in various applications, such as telecommunications, medical diagnostics, and remote sensing. - Mid-infrared light (MIR): The MIR range extends from 1,400 nm to 3,000 nm. MIR is widely used in spectroscopy, thermal imaging, and chemical analysis. - Far-infrared light (FIR): This range spans from 3,000 nm to 1 mm. FIR is primarily used in heating applications, such as in cooking and industrial processes.
