Summary and References
The exact index of refraction for a glass at any wavelength can be returned by ZEMAX in a number of different ways:
- The Dispersion Diagram – plots the index of refraction as a function of wavelength for any glass.
- Reports - Both the Surface Data report and the Prescription Data report will calculate the index at each design wavelength. The Prescription Data report shows the index data for all surfaces.
- The Merit Function – The INDX operand will return the index for any specified surface and wavelength.
- ZPL – The flexible OPEV() function can be used in a macro to call up the INDX operand calculation.

Short, and pins down the topic to the point.
