2. Sellmeier equation - Wikipedia

   en.wikipedia.org/wiki/Sellmeier_equation

   The Sellmeier equation is an empirical relationship between refractive index and wavelength for a particular transparent medium. The equation is used to determine the dispersion of light in the medium. It was first proposed in 1872 by Wolfgang Sellmeier and was a development of the work of Augustin Cauchy on Cauchy's equation for modelling ...

3. Refractive index - Wikipedia

   en.wikipedia.org/wiki/Refractive_index

   For a more accurate description of the wavelength dependence of the refractive index, the Sellmeier equation can be used. [29] It is an empirical formula that works well in describing dispersion. Sellmeier coefficients are often quoted instead of the refractive index in tables.

4. Fused quartz - Wikipedia

   en.wikipedia.org/wiki/Fused_quartz

   This equation is valid between 0.21 and 3.71 μm and at 20 °C. [17] Its validity was confirmed for wavelengths up to 6.7 μm. [ 4 ] Experimental data for the real (refractive index) and imaginary (absorption index) parts of the complex refractive index of fused quartz reported in the literature over the spectral range from 30 nm to 1000 μm ...

5. Wolfgang Sellmeier - Wikipedia

   en.wikipedia.org/wiki/Wolfgang_Sellmeier

   Wolfgang Sellmeier was a German theoretical physicist who made major contributions to the understanding of the interactions between light and matter. [1] In 1872 he published his seminal work Ueber die durch die Aetherschwingungen erregten Mitschwingungen der Körpertheilchen und deren Rückwirkung auf die ersteren, besonders zur Erklärung der Dispersion und ihrer Anomalien. [2]

6. Dispersion (optics) - Wikipedia

   en.wikipedia.org/wiki/Dispersion_(optics)

   This makes dispersion management extremely important in optical communications systems based on optical fiber, since if dispersion is too high, a group of pulses representing a bit-stream will spread in time and merge, rendering the bit-stream unintelligible. This limits the length of fiber that a signal can be sent down without regeneration.

7. Cauchy's equation - Wikipedia

   en.wikipedia.org/wiki/Cauchy's_equation

   In optics, Cauchy's transmission equation is an empirical relationship between the refractive index and wavelength of light for a particular transparent material. It is named for the mathematician Augustin-Louis Cauchy , who originally defined it in 1830 in his article "The refraction and reflection of light".

8. Free ad-supported streaming television - Wikipedia

   en.wikipedia.org/wiki/Free_ad-supported...

   Free advertising-supported streaming television (FAST) is a category of streaming television services which offer traditional linear television programming ("live TV") and studio-produced movies without a paid subscription, funded exclusively by advertising akin to over-the-air or cable TV stations.

9. Refractive index and extinction coefficient of thin film ...

   en.wikipedia.org/wiki/Refractive_index_and...

   A. R. Forouhi and I. Bloomer deduced dispersion equations for the refractive index, n, and extinction coefficient, k, which were published in 1986 [1] and 1988. [2] The 1986 publication relates to amorphous materials, while the 1988 publication relates to crystalline.
