Optical radiation measurements, commonly referred to as photonics, is the technology of generating and harnessing light, and other forms of radiant energy, particularly in the visible and near infrared light spectrum. Photonics applications include assessment of the emission, transmission, detection, amplification, and modulation of light energy radiance and surface irradiance. Photonics is deeply rooted in a broad range of science and technology applications, including laser manufacturing, biological and chemical sensing, medical diagnostics and therapy, display technology, and optical computing. Throughout this array of applications the importance of measuring the precise quality and intensity of light varies, but can be critical depending upon the application’s technical requirements.

"The term photonics also reflects the importance of the photon nature of light in describing the operation of many optical devices." [from Saleh & Teich, Fundamentals of Photonics]
