fotometriák

Fotometriák is a term of Greek origin, combining "photos" meaning light and "metron" meaning measure. It refers to the scientific study and measurement of light and its properties. More specifically, photometry deals with quantifying the intensity of light and its distribution, as well as how light interacts with matter. This encompasses various aspects, including the measurement of luminous flux, luminous intensity, illuminance, and luminance.

The field of photometry is crucial in many scientific and industrial applications. It plays a role in understanding how light sources function, such as lamps and LEDs, and how they illuminate environments. In astronomy, photometry is used to measure the brightness of celestial objects, which helps in determining their properties like size, temperature, and distance. It is also essential in the development and testing of optical instruments, cameras, and display technologies. Furthermore, photometry is applied in fields like color science, industrial inspection, and medical imaging, where precise light measurements are required. Different photometers are employed for these measurements, each designed to capture specific aspects of light's behavior.
