Figure 6. Chromatism is due to the wavelength dependence of the index of refraction and produces coloured, diffuse and/or elongated images. For simplicity reasons, the off-axis image in the figure above is shown with pure lateral chromatism in reality both axial and lateral chromatisms would combine.

The polymers were characterised by NMR and matrix assisted laser desorption/ ionisation-time of flight MS (MALDI-TOF MS) [92]. They have variable indices of refraction (from 1.45-1.52), Tg from 265-350 °C, and long-term thermal stability at 623 K. The dependence of refractive index on wavelength were also measured and the constants of copolymerisation reaction were determined [92]. End-group analysis has been a reliable asset in PFCB chemistry and in particular for copolymerisation studies [92]. 

Strictly speaking, their dependence on A is determined by the wavelength dependence of the index of refraction of the medium. 

Here, the wavelength of the laser light is A, and is a correction term due to the wavelength dependence of the refractive index of the etalon material ( = 0.034 at 514.5 nm when fused silica etalons are used to achieve the necessary delay, or = 0 when a lens combination is used). The optical correction term Av/v results from the change in refractive index of the window material with shock stress (Barker and Hollenbach, 1970). If the measure-... 

As an example of the application of this result, the minimum aberration for acoustic imaging with a wavelength of 25 fan at a depth of 0.5 mm below the surface of a material of refractive index n = 0.25 would be given by h/sb = 0.7, so that the optimum lens angle would be 0opt = 8.3°. This result depends rather weakly on Sb, so that halving the depth would increase the optimum angle by less than 1 °. 

In calculating efficiency factors for absorption and scattering, the wavelength dependence of both the real and imaginary parts of the refractive index must be considered. 

Material Dispersion—The dispersion associated with a non-monochro made light source due to the wavelength dependence of die refractive index of a material or of the light velocity in this material. 

When particles of refractive index significantly different from that of the suspending medium contain a dimension greater than c. A/4, extinction at intermediate angles is possible and maxima and minima of scattering can be observed at different angles. The location of such maxima and minima will depend on the wavelength, so that with...
