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.
The spectrophotometer is a complex instrument used in measuring the absorbance of biomolecules within the ultraviolet and visible light spectrum, similar to the one found in the laboratory.he same goes when measuring visible light absorbance. This is to prevent interference of unnecessary wavelengths in the incident light on the sample. Following the light source is a monochromator, the purpose of which is to filter light and select a specific wavelength by using either a prism or a diffraction grating.
