NSC

Non-sequential Component (NSC) objects are 3D objects used in non-sequential ray tracing. NSC objects can be defined in non-sequential mode and in mixed mode:

NSC objects are defined in non-sequential mode using the Non-sequential Component Editor. See "NSC ray tracing in non-sequential mode" for more information.

NSC objects are defined in mixed mode using a Non-sequential Component surface in the Lens Data Editor. See "NSC ray tracing in mixed mode" for more information.
