GlossaryNear-Infrared Light (NIR light)

refers to wavelengths just beyond visible light, around 700-2500 nm

Near-Infrared Light (NIR) refers to a segment of the electromagnetic spectrum with wavelengths just beyond the visible light range, typically from about 700 to 2500 nanometers. It is commonly used in medical imaging, remote sensing, and therapeutic applications due to its ability to penetrate tissues more deeply than visible light, making it useful for non-invasive diagnostics and treatments.
