IR 850 nm, or infrared at 850 nanometers, is a specific wavelength within the infrared spectrum that has gained significant attention in various industries due to its unique properties and applications. This wavelength falls within the mid-infrared region, where it is less likely to be absorbed by water vapor, making it ideal for long-range sensing and communication. This article delves into the industry's perspective on IR 850 nm, exploring its uses, benefits, challenges, and future prospects.

Introduction to IR 850 nm

Infrared radiation, often referred to as IR, is a form of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves. The IR spectrum is divided into several regions, including near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). IR 850 nm specifically belongs to the MIR region, which spans from about 2.5 to 25 micrometers. This region is particularly interesting for its interaction with various materials and its potential applications in technology.

Applications of IR 850 nm
