In the vast and intricate world of photonics and optical engineering, radiometry plays a crucial role. It is the science and technology of measuring the radiant power (energy per unit time) of electromagnetic radiation, particularly in the visible and infrared parts of the spectrum. At its core, radiometry involves quantifying the optical radiation that surrounds us or is emitted by various sources, from the sun and stars to lasers and LEDs.
