WebThe refractive indices of pure water and ice, as functions of wavelength, are needed to determine the scattering and absorption properties of cloud particles. The complex refractive index m (λ)= mr (λ)+i mi (λ) where λ is the free-space wavelength, mr is the real part of the refractive index, and mi is the imaginary part. WebThe index of refraction and Abbe number of a glass are typically used by designers as degrees of freedom when designing systems. ... The leading letters in the glass name characterize an important chemical element used in the glass type: F - Fluorine, P – Phosphorus, B – Boron, BA – Barium, LA – Lanthanum. ... Webare also used to predict optical properties from chemical composi - tions, which is of value in developing new materials, particularly borate optical crystals (Qin and Li 2011). The refractive index is also an important parameter of lasers and is required, for instance, in the analysis of the radiative properties of Ln 3+ ions (Han et al. 2012). grasping sparrow tail
