... This method of setting the channels provides nice size intervals, but masks the fact that there is a fair degree of uncertainty associated with these size intervals, e.g. a certain fraction of particles in size range 11 - 14 m may actually get sized in the 14-17 m size range, while there will be s ...

... Each wavelength is 360o, so ΔN=496.41 means Δφ=ΔNx360o=0.41x360o=148o •How thick should the glass be so that the beams are exactly out of phase at the exit (destructive interference!) ΔN=D/ λs− D/ λg= (D/ λ)(n2-n1)=0.31 (D/ λ)=m+1/2 A thickness D=(m+0.5) 2.02 µm would make the waves OUT of phase. Fo ...

Dispersion staining
The optical properties of all liquid and solid materials change as a function of the wavelength of light used to measure them. This change as a function of wavelength is called the dispersion of the optical properties. The graph created by plotting the optical property of interest by the wavelength at which it is measured is called a dispersion curve.The dispersion staining is an analytical technique used in light microscopy that takes advantage of the differences in the dispersion curve of the refractive index of an unknown material relative to a standard material with a known dispersion curve to identify or characterize that unknown material. These differences become manifest as a color when the two dispersion curves intersect for some visible wavelength. This is an optical staining technique and requires no stains or dyes to produce the color. Its primary use today is in the conformation of the presence of asbestos in construction materials but it has many other applications.
