WebWith respect to the measurement of daylight illumination, the figures for high luminance levels, i.e., photopic vision, are the appropriate ones (see any recent text- book on photometry). Natural illumination (daylight or skylight—analo- gous to total and diffuse radiation) is normally meas- ured with a photometer resembling a pyranometer.
A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an electric current using a photoresistor, photodiode, or photomultiplier. Photometers measure: … See more Before electronic light sensitive elements were developed, photometry was done by estimation by the eye. The relative luminous flux of a source was compared with a standard source. The photometer is placed such that the … See more Most photometers detect the light with photoresistors, photodiodes or photomultipliers. To analyze the light, the photometer may … See more Photometers are used to determine the correct exposure in photography. In modern cameras, the photometer is usually built in. As the illumination of different parts of the picture varies, … See more These are optical instruments for measurement of the absorption of light of a given wavelength (or a given range of wavelengths) of … See more Some photometers measure light by counting individual photons rather than incoming flux.
