IR 850 nm, or infrared at 850 nanometers, has emerged as a crucial wavelength in various industries due to its unique properties and applications. This article delves into the world of IR 850 nm, exploring its significance, applications, and future prospects.
Introduction to IR 850 nm
Infrared (IR) radiation is a form of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of microwaves. The IR spectrum is divided into several regions, including near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). IR 850 nm falls within the NIR region, which is characterized by wavelengths ranging from 700 to 1400 nm. This particular wavelength has gained significant attention due to its ability to penetrate certain materials and its compatibility with various detection technologies.
