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 measure the light after it has passed through a filter or through a monochromator for determination at defined See more A reflectance photometer measures the reflectance of a surface as a function of wavelength. The surface is illuminated with white light, and the reflected light is measured after passing through a monochromator. This type of measurement has … See more Spectrophotometry in infrared light is mainly used to study structure of substances, as given groups give absorption at … See more Some photometers measure light by counting individual photons rather than incoming flux. The operating principles are the same but the … See more Photometers are used to determine the correct exposure in photography. In modern cameras, the photometer is usually built in. As the … See more These are optical instruments for measurement of the absorption of light of a given wavelength (or a given range of wavelengths) of coloured substances in solution. From the light absorption, Beer's law makes it possible to calculate the concentration of the … See more Web109752. Overview. Enjoy high measurement quality with great simplicity.
