In astronomy, the term spectrophotometry refers to the measurement of the spectrum of a celestial object in which the flux scale of the spectrum is calibrated as a function of wavelength, usually by comparison with an observation of a spectrophotometric standard star, and corrected for the absorption of light by the Earth's atmosphere.
A spectrophotometer is an instrument which is used to measure the intensity of electromagnetic radiation at different wavelengths. Important features of spectrophotometers are spectral band with and the range of absorption or reflectance measurement. Then, add the solute which would be the blank for the experiment. 2  It is important not to add water to the blank so that it wonât affect the accuracy of the results. 3  As a next step, the spectrophotometer is set to the desired wavelength. 4  Insert the blank cuvette, making sure that the arrow is aligned each time.
