where M is the beam magnification provided by the beam expander that multiplies the angular dispersion provided by the diffraction grating. In practice, M can be as high as 100-200. [8] [11] When the dispersion of the multiple-prism expander is not equal to zero, then the single-pass linewidth is given by [5] [8]

The calculation of glass properties allows "fine-tuning" of desired material characteristics, e.g., the refractive index. [1]The calculation of glass properties (glass modeling) is used to predict glass properties of interest or glass behavior under certain conditions (e.g., during production) without experimental investigation, based on past data and experience, with the intention to save ...
where ω is the angular frequency and k is the wavevector with magnitude | k | = k, equal to the wave number. Divide by ℏ {\displaystyle \hbar } and take the square root. This gives the relativistic frequency dispersion relation : ω ( k ) = k 2 c 2 + ( m 0 c 2 ℏ ) 2 . {\displaystyle \omega (k)={\sqrt {k^{2}c^{2}+\left({\frac {m_{0}c^{2 ...
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.
Dispersion Technology Inc is a scientific instrument manufacturer located in Bedford Hills, New York. [1] It was founded in 1996 by Philip Goetz (former chairman , retired in 2010) and Dr. Andrei Dukhin (current CEO). [ 3 ]
The convection–diffusion equation can be derived in a straightforward way [4] from the continuity equation, which states that the rate of change for a scalar quantity in a differential control volume is given by flow and diffusion into and out of that part of the system along with any generation or consumption inside the control volume: + =, where j is the total flux and R is a net ...
In the technical terminology of gemology, dispersion is the difference in the refractive index of a material at the B and G (686.7 nm and 430.8 nm) or C and F (656.3 nm and 486.1 nm) Fraunhofer wavelengths, and is meant to express the degree to which a prism cut from the gemstone demonstrates "fire". Fire is a colloquial term used by ...
