This article aims to provide an in-depth introduction to IR 950nm, exploring its properties, applications, and the technology behind it.
Introduction to Infrared Radiation
Infrared radiation, often simply referred to as IR, is a form of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. The electromagnetic spectrum spans from gamma rays to radio waves, with infrared falling somewhere in the middle. IR radiation is invisible to the human eye but can be detected and utilized in various ways.
The infrared spectrum is divided into three regions: near infrared (NIR), mid-infrared (MIR), and far infrared (FIR). The near infrared range spans from approximately 0.75 to 3 micrometers, while the mid-infrared range extends from 3 to 50 micrometers, and the far infrared range goes from 50 to 1000 micrometers. Each region has unique properties and applications.
