Webphotometer. 1. a device for measuring the intensity of infrared, ultraviolet, or visible light. 2. a device for testing the sensitivity of the eye to light by determining the light minimum. WebJul 15, 2024 · Hence a filter or monochromator is to be used. A simple flame photometer contains a filter wheel and when a particular elements has to be analysed the specific filter is selected. 3.DETECTOR :-The radiation emitted by the elements is mostly in the visible region. Hence conventional detectors like photo voltaic cell or photo tubes can be used. is allstate closed today

"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 wavelengths or for analysis of the spectral distribution of the light. See more 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 … See more Some photometers measure light by counting individual photons rather than incoming flux. The operating principles are the same but the results are given in units such as photons/cm … 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 … See more Spectrophotometry in infrared light is mainly used to study structure of substances, as given groups give absorption at defined wavelengths. Measurement in … 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 … See more Photometers are used to determine the correct exposure in photography.
