Spectrophotometer \Spec`tro*pho*tom"e*ter\, n. [Spectrum
photometer.]
1. (Opt.) An instrument for measuring or comparing the
intensities of the colors of the spectrum.
[1913 Webster]

2. (Chem., Physics) An analytical instrument for measuring
the degree of absorption of light at different wavelengths
by a chemical substance. A specific pattern of absorption
intensities at a series of wavelengths is a characteristic
of each different chemical substance.
