photometer
[ fษสหtษmษtษ ]
scientific measurement
A photometer is an instrument used to measure the intensity of light or the illumination in a specified area. It can be used in various fields, including photography, astronomy, and environmental science. Photometers can quantify the amount of light in different units, such as lux or foot-candles, depending on their design and intended application. Some photometers are designed for specific tasks, while others are more versatile instruments that can accommodate a range of light sources.
Synonyms
illuminance meter, light meter, lux meter.
Examples of usage
- The scientist used a photometer to measure the light intensity in the lab.
- He calibrated the photometer before conducting the experiment.
- Photometers are essential tools in evaluating indoor lighting conditions.

Etymology
The term 'photometer' originates from the combination of two Greek words: 'photo', meaning light, and 'metron', meaning measure. The invention of the photometer can be traced back to the early 19th century when scientists sought to quantify light for various applications, including studies of light's properties and its effects on materials. Early photometers typically involved comparative methods, where two light sources were evaluated side by side to assess their brightness. Over time, advancements in technology influenced the design and functionality of photometers, leading to more precise and portable devices. With the rise of industries such as photography and cinematography, improved photometers became crucial for achieving proper exposure and illumination standards. Nowadays, photometers are widely used in various sectors, including research, manufacturing, and environmental monitoring.
