We present wavelength- and temperature-dependent refractive index equations for 5% MgO-doped congruent PPLN and for 1% MgO-doped stoichiometric PPLN crystals valid for a wide spectral and temperature range. The dispersion equations were derived from quasi-phase-matched nonlinear interactions with these ...
Therefore, the refractive index (n) is inversely proportional to the wavelength and also to the speed of light. This means the greater the wavelength, the lower the refractive index. This relationship is represented by the equation: v(λ) = c/n(λ) However, for in...

Researchers often provide us with data in a format ready-to-include in the refractiveindex.info dataset as soon as the data are first published. 2. Data extraction (a) Dispersion formula: When the linear refractive index as a function of wavelength is given as a dispersion formula, the ...
in ordinary glass the refractive index for violet light is about one percent greater than that for red light. A consequence of this phenomenon is that each wavelength experiences a slightly different degree of refraction when a heterogeneous light beam containing more than one frequency enters or le...
Generation of these values was based on a dispersion equation which best fits selected data sets covering wide temperature and wavelength ranges. Temperature derivative of refractive index was simply calculated from the first derivative of the equation with respect to temperature. The results are in ...
scale of aPapiliobutterfly (Graphium sarpedon) using Jamin–Lebedeff interference microscopy. They determined the cuticle'srefractive indexncto be 1.572, 1.552, and 1.541 at wavelengths of 400nm, 500nm, and 600nm, respectively. The slight wavelength dependence is described well byCauchy's equation...
2. Relationship with Wavelength: The speed of light in a medium is related to the wavelength (λ) of the light. According to the wave equation, the speed of light in a medium can be expressed as: v=f⋅λ where f is the frequency of the light wave. 3. Frequency and Wavelength: Th...
even if similar features have been found for their wavelength dependence39,40. Equation (1) is believed to provide a suitable model for the RI intact RBCs because the membrane is very thin compared to the wavelength of visible light14and has a low volume fraction16. In addition to the intri...
The wavelength-dependent refractive index of a transparent optical material can often be described analytically with a Sellmeier formula, which contains several empirically obtained parameters. Extended versions of such equations also describe the temperature dependence; such an equation has been used for ...
