Infrared (IR) research focuses on the study and application of electromagnetic radiation with wavelengths longer than those of visible light, usually ranging from 0.75 to 1000 micrometers. This type of radiation is commonly used in various fields such as astronomy, remote sensing, medical imaging, and military applications. Infrared research aims to understand the properties of infrared radiation, develop new technologies for its detection and imaging, and explore its potential uses in different scientific and industrial applications.
