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.
