photometer
This term is a technical noun used primarily in physics, astronomy, and optics. It describes a specific tool for quantifying light intensity, distinguishing it from a lux meter, which measures illuminance on a surface, or a spectrometer, which analyzes the wavelength of light.
In professional and academic registers, the word is used with high precision to describe the hardware used in empirical measurements. It is rarely encountered in casual conversation, appearing almost exclusively in scientific literature or laboratory manuals.
