spectrophotometry

listen to the pronunciation of spectrophotometry
English - English
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
An estimation of coloring matter in a solution (CMD 1997)
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
{i} measurement of the intensity of colors in the spectrum
The art of comparing, photometrically, the brightness of two spectra, wave length by wave length; the use of the spectrophotometer
The science and techniques associated with the use of spectrophotometers
spectrophotometer
Device for the measurement of spectral transmittance spectral reflectance, or relative spectral emittance
spectrophotometer
An instrument used to measure the intensity of electromagnetic radiation at different wavelengths
spectrophotometer
A reflectance meter that partitions the visible spectrum into sections and measures the reflectance in each section separately
spectrophotometer
An instrument for measuring or comparing the intensites of the colors of the spectrum
spectrophotometer
A high-end device that measures a color's wavelength
spectrophotometer
An instrument that measures the characteristics of light reflected from our transmitted through an object, which is interpreted as spectral data
spectrophotometer
A device for measuring the relative amounts of radiant energy or radiant flux as a function of wavelength
spectrophotometer
a photometer for comparing two light radiations wavelength by wavelength
spectrophotometer
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)
spectrophotometer
An instrument that measures the amount of light a color sample reflects or transmits at each wavelength, producing spectral data
spectrophotometer
Instrument used to measure the index of refraction of colour
spectrophotometer
An instrument that measures the amount of a given wavelength of energy that is transmitted or absorbed by a substance
spectrophotometer
A photometer which measures the intensity of radiation as a function of the frequency (or wavelength) of the radiation
spectrophotometer
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
spectrophotometer
A device for measuring color at a variety of wavelengths throughout the visible spectrum
spectrophotometer
an instrument for plotting lamp output or measuring color values; can be calibrated for UV
spectrophotometer
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
spectrophotometer
{i} device for measuring the relative intensity of parts of a spectrum
spectrophotometer
Device for the measurement of spectral transmittance, spectral reflectance, or relative spectral emittance
spectrophotometer
An instrument used to measure energy in a sample of light or pigmented surface
spectrophotometer
An instrument for measuring the intensity of radiation absorbed at different wavelengths
spectrophotometer
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
