Diffractive and Generalized Phase Surfaces
===========================================

This section provides examples of diffractive and generalized phase surfaces.

Diffractive Surfaces
--------------------

This section contains examples of optical systems that utilize diffraction gratings, including spectrometer designs. These examples demonstrate grating parameter specification and wavelength dispersion modeling. These examples are intended to be illustrative and not exhaustive. For a complete list of available functions and classes, please refer to the `Optiland` API.

Generalized Phase Surfaces
--------------------------

This section contains examples of surfaces with generalized phase profiles. These surfaces can be used to model a wide range of optical elements, including lenses, gratings, and more complex phase structures. The examples below illustrate the creation and application of linear and radial phase profiles within optical systems.
