Infra rouge, literally “below red,” designates the region of the electromagnetic spectrum with wavelengths longer than visible light, ranging from approximately 700 nanometers to 1 millimeter. This portion of the spectrum is often associated with heat radiation and is crucial in numerous scientific disciplines, including astrophysics, thermal imaging, spectroscopy, and remote sensing. Understanding infra rouge phenomena is vital for applications ranging from medical diagnostics – detecting temperature variations indicative of illness – to industrial quality control, identifying material defects, and environmental monitoring, assessing thermal pollution. Research into infra rouge technology continually advances fields like non-destructive testing, night vision systems, and fiber optic communications, relying on concepts like black-body radiation, infrared detectors (bolometers, thermopiles), and radiative transfer. The study of infra rouge also intersects with areas like molecular vibrations and material science, providing insights into substance composition and properties.
