WebFeb 12, 2024 · Spectrophotometry is a measurement of how much a chemical substance absorbs or transmits. Spectrophotometry is widely used for quantitative analysis in various areas (e.g., chemistry, physics, biology, biochemistry, material and chemical engineering, clinical applications, industrial applications, etc). Any application that deals with chemical ... 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, advanced photometers measure the light intensity in different parts of 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 … 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 or photons·cm ·sr rather than W/cm or W·cm ·sr . Due to their … See more A reflectance photometer measures the reflectance of a surface as a function of wavelength. The surface is illuminated with white light, and … 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
