But what does a spectrophotometer actually do? Spectrophotometers are instruments used to send electromagnetic radiation into a given target to measure the resulting interaction of energy and the target.
An early example of a spectroscope. Prisms split light by refraction; the resulting spectrum is measured by the spectroscope. In astronomy, a spectroscope may be used in conjunction with a telescope. A spectrophotometer measures how much light is reflected off of -- or absorbed by -- an object. spectroscope is a scientific instrument that splits light into its different wavelengths, which humans see as different colors.
