Definition of spectrophotometry in English English dictionary
The quantitative analysis of electromagnetic spectra by use of a spectrophotometer; especially in order to determine the structure or quantity of a substance
Measurements of the relative amounts of radiant flux at each wavelength of the spectrum
Branch of spectroscopy dealing with measurement of radiant energy transmitted or reflected by a body as a function of wavelength. The measurement is usually compared to that transmitted or reflected by a system that serves as a standard. In chemistry and physics, different types of spectrophotometers cover wide ranges of the electromagnetic spectrum: ultraviolet (UV), visible light, infrared (IR), or microwave. UV spectrophotometry is particularly useful in detecting and quantifying colourless substances in solution. IR spectrophotometry is used mostly to study the molecular structures of complex organic compounds. In astronomy and astrophysics, spectrophotometric studies also include the X-ray and gamma ray ranges of the spectrum. See also colorimetry
A photometric device for the measurement of spectral reflectance, transmittance or emission (monitors) The measured values are reported graphically (the spectral curve of the measured object) and numerically (at intervals across the visible spectrum)
An instrument used to measure the amount of light reflected from a specimen when illuminated by a controlled light source This measurement generates a spectral curve (fingerprint) of a product, which can be used in the numerical identification and the calculation of color difference between samples
A spectrophotometer is a detector instrument that measures the amount of monchromatic light passing through a solution by means of an adjustable monochromator such as a prism or diffraction grating
A precision measuring instrument used to measure wavelengths of light The readings from a spectrophotometer are use to generate spectral reflectance curves as a way to define and describe color information Spectrophotometers are typically used to create ICC printer profiles
