fotometrisen

Fotometrisen is a term derived from the Greek words "photo" meaning light and "metron" meaning measure. It refers to the process or technique of measuring light. This measurement can encompass various aspects of light, including its intensity, brightness, color, and distribution.

In practice, photometry is applied in numerous scientific and technical fields. It is fundamental in astronomy for determining the brightness of celestial objects and in photography for controlling exposure settings. In lighting design, photometry is used to assess the illuminance provided by artificial light sources to ensure adequate visibility and comfort. Spectrophotometry, a related field, measures light intensity as a function of wavelength, allowing for the analysis of the spectral properties of light and the materials that interact with it. Devices used for photometric measurements are called photometers. These instruments can range from simple light meters to sophisticated scientific equipment. The principles of photometry are essential for understanding and manipulating light in a wide array of applications, contributing to advancements in technology, research, and daily life.
