Polygon objects are very flexible user defined objects which may be used within ZEMAX.  Defined by a simple ASCII text file, you may define any object by a series of vertices which are then connected using either rectangle or triangle commands.  Each face generated in the POB file can be assigned a unique face group, or perhaps one which is common to other faces of the object.  This way, the user has the flexibility of defining different coating and scattering properties do different faces of the faceted object.
