SpectrophotometerNoun1. A photometer for comparing two light radiations wavelength by wavelength. Source: WordNet 1.7.1 Copyright © 2001 by Princeton University. All rights reserved. |
Note: Spectrophotometer \Spec`tro*pho*tom"e*ter\, noun. [Spectrum photometer.]. (Websters 1913) |
| Domain | Definition |
Aerospace | A photometer which measures the intensity of radiation as a function of the frequency (or wavelength) of the radiation. Also called spectroradiometer. See Dobson spectrophotometer.In one design, radiation enters the spectrophotometer through a slit and is dispersed by means of a prism. A bolometer having a fixed aperture scans the dispersed radiation so that the intensity over a narrow wave band is obtained as a function of frequency. (references) |
Chemistry | Photometer adapted to measure the spectral distribution of the luminous flux in a beam of light ; photometer adapted to measure the spectral distribution of the luminous flux in a beam of light; instrument for measuring the ratio of two spectral radiometric quantities.

Mining | An instrument to detect very slight differences in color of solutions of different chemicals and thus measure the quantity of the chemical present. It consists of a light source, an optical prism for providing monochromatic light; i.e., light of a single wavelength only, and a device for measuring the intensity of the light beam after it has passed through the solution. Traces of aluminum in steel may be determined in this way.Also called spekker. (references) |
Science | A device for measuring the relative amounts of radiant energy or radiant flux as a function of wavelength. (references) |
