Dispersion Diagram
Plots index of refraction as a function of wavelength for up to 4 different glasses.
Glass 1 - 4The name of the glass for which the data is plotted. Up to 4 different glasses may be selected.
Minimum WaveDefines the minimum wavelength for which the data should be plotted.
Maximim WaveDefines the maximum wavelength for which the data should be plotted.
Minimum IndexDefines the minimum index for which the data should be plotted. Enter zero for automatic scaling.
Maximum IndexDefines the maximum index for which the data should be plotted. Enter zero for automatic scaling.
Use Temperature, PressureIf checked, then the change in index due to temperature and pressure effects will be considered.
Discussion
This feature is useful for comparing the dispersion curves between different glasses. Table glass files (see "Using table glasses") are listed at the bottom of the various "Glass" controls.
If the minimum and maximum wavelength inputs are both zero, then the left X-axis of the plot will be determined by the minimum wavelength for which data are available for any of the input glasses (even if other glasses do not have data at this wavelength) and the right X-axis of the plot will be determined by the maximum wavelength for which data are available for any of the input glasses (even if other glasses do not have data at this wavelength).
