WebSome typical refractive indices for yellow light (wavelength equal to 589 nanometres [10 −9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, 1.655; and diamond, 2.417. The variation of refractive index with wavelength is the source of chromatic aberration in lenses. WebJan 19, 2024 · If using a ‘dry’ (non-immersion) objective the maximum NA of the objective will be 0.95 (as air has a refractive index of 1.0). Abbe’s diffraction formula for lateral (XY) resolution is: d = λ/ (2NA) where λ is the wavelength of light used to image a specimen.
WebFigure 4: Finite Difference uniform mesh. Formally, we have from Taylor expansion: Subtracting Equation 51 from Equation 51 and neglecting higher order terms: Thus, for TE modes we get. Here we consider: By substituting Equation 55 and Equation 56 into Equation 54, we get: Therefore, we can rewrite Equation 50 for TE modes as. WebAbstract: A numerical method for the analysis of the absorption spectrum and the refractive index change due to an external electric field in quantum-well structures is presented. The finite-element method and the variational method are used to obtain the subband and the exciton energies in a quantum-well structure, respectively.
Web(509) and (510) are called retarded potentials. It is often useful to adopt the following notation (511) The square brackets denote retardation (i.e., using the retarded time instead of the real time). Using this notation Eqs.
