How is reflectivity measured
WebTotal reflectance is measured over a broad wavelength range (250 < λ< 2500 nm) that is applicable to ultraviolet, visible, and near-infrared instrumentation. Lambertian … WebThis method was used to measure a facet reflectivity of R 2 = 0.0151 (+0.0018/-0.0032) [ R 2 = 0.00592 (+0.00085/-0.00123)] for a commercially antireflection-coated facet of a laser diode with a center wavelength of 795 nm (935 nm). The results of the reflectivity measurements based on the threshold current as a function of the external mirror ...
