spectrophotometer

 [spek″tro-fo-tom´ĕ-ter]
1. an apparatus for measuring light sense by means of a spectrum.
2. an apparatus for determining the quantity of coloring matter in a solution by measurement of transmitted light. See also colorimeter.

spec·tro·pho·tom·e·ter

(spek'trō-fō-tom'ĕ-tĕr),
An instrument for measuring the intensity of light of a definite wavelength transmitted by a substance or a solution, giving a quantitative measure of the amount of material in the solution absorbing the light; a colorimeter with a choice of wavelength and photometric measurement.
[spectro- + photometer]

spectrophotometer 

An instrument for measuring the relative intensities of the spectrum, wavelength by wavelength. Specifically it measures the spectral transmission factor (i.e. the ratio of radiant flux transmitted through a medium to that incident on it) of a medium for a given wavelength. This factor is usually plotted as a graph against many wavelengths providing a spectral transmission curve. Ophthalmic lenses, contact lenses and any other substances (e.g. tear lipids) through which light may be passed can thus be analysed. See density.

spectrophotometer

an apparatus for determining the ability of a solution to absorb light of a specific wavelength by measuring the transmitted light.
