This application note presents the basics of optical spectroscopy. It describes the prism and light separation, the prism-based spectroscope, the reflection grating-based spectroscope and the use of ...

Optical spectroscopy has helped scientists explore several new areas of nanocomposite research. In this article, the role of optical spectroscopy in polymer research is discussed. Optical spectroscopy ...

Surface analysis techniques such as quantitative depth profiling (QDP), usually require sophisticated and expensive instruments and tend to have very high spatial resolution. There is a widely held ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Through a combination of high-pressure experiments and optical spectroscopy, physicists have revealed new insights into the structural forms of solid methane. Led by Mengnan Wang at the University of ...
