Ultraviolet–Visible Spectrophotometry

Encyclopedic Dictionary of Archaeology, 2018
UV–Vis spectrophotometry is routinely used in the quantitative chemical analysis of solutions. In this article, applications to solid-state spectroscopy are described. This method detects optical transmittance/reflectance, i.e., intensity ratios of the transmitted/reflected light from a sample to the incident monochromatic light in the visible and ...

Homochromatic Spectrophotometry in the Extreme Ultraviolet

Journal of the Optical Society of America, 1930
The d-log t curves of typical fast, medium, and slow emulsions when coated with oils fluorescing in the blue, near ultraviolet, and far ultraviolet respectively, have been studied in the region 900 to 5000 Angstroms by means of a vacuum spectrograph designed especially for photographic photometry, together with ordinary quartz spectrographs.

Ultraviolet-Visible Spectrophotometry

2020
Ultraviolet (UV) and visible spectrophotometry have been utilized in forensic toxicology for both qualitative and quantitative analysis. Lambert discovered that for monochromatic radiation, absorbance was directly proportional to the path length of the incident light through the material.
