Optical reflectivity
WebOptical reflection spectroscopy in the mid- and near-IR (infrared) range occupies an important complementary position for interface studies. Many reflection techniques permit in situ applications, and if applied in the mid-IR, result in quantitative and structural information on a molecular level. WebThe calibration of a reflectometer becomes critical when reflectance values very close to unity (perfect reflectance) are to be measured. Refined methods can be used to optimize such calibration procedures; for example, one may use an optical setup where one can alternately measure the optical power of light reflected at the sample and the power of …
