... been that a great many theories have been proposed, only to be discarded. About 2,000 years ago, the characteristics of light were defined by the way it behaved under a variety of conditions (geometric optics). The premise was that light consists of rays that move outward from their source in straig ...

Shaping the focal intensity distribution using spatial coherence

... Although light encountered under many practical circumstances is partially coherent, the intensity near focus of such wave fields has been studied in relatively few cases [1–5]. The correlation properties of focused partially coherent fields have been examined in [6,7], where it was shown that the c ...

Ultraviolet–visible spectroscopy



Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
