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 that measures the amount of light a color sample reflects or transmits at each wavelength, producing spectral data
An instrument that measures the amount of a given wavelength of energy that is transmitted or absorbed by a substance
A photometer which measures the intensity of radiation as a function of the frequency (or wavelength) of the radiation
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 device for measuring color at a variety of wavelengths throughout the visible spectrum
an instrument for plotting lamp output or measuring color values; can be calibrated for UV
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
