In this article, we will delve into the intricacies of 940nm IR light, exploring its characteristics, applications, and the technological advancements that have made it a cornerstone in modern industries.

Introduction to Infrared Light

Infrared light is a form of electromagnetic radiation that has a longer wavelength than visible light but shorter than microwave radiation. It falls just beyond the red end of the visible spectrum and is invisible to the human eye. The term “infrared” comes from the Latin “infra,” meaning “below,” and “lumen,” meaning “light,” reflecting its position below the visible light spectrum.
