IR 950nm, or infrared at 950 nanometers, has become an increasingly significant wavelength in various industries due to its unique properties and applications. This article aims to provide a comprehensive introduction to the IR 950nm spectrum, its characteristics, and its applications across different sectors.

Introduction to IR 950nm

Infrared radiation, often referred to as IR, is a type of electromagnetic radiation with wavelengths longer than visible light. The IR spectrum is divided into several regions, including near-infrared (NIR), short-wavelength infrared (SWIR), and mid-infrared (MIR). The 950nm wavelength falls within the SWIR region, which is typically characterized by wavelengths between 1.2 and 3.0 micrometers. This specific wavelength has gained attention due to its ability to penetrate certain materials and its potential applications in various fields.
