Nonimaging Optics has shown that it achieves the theoretical limits by utilizing thermodynamic principles rather than
conventional optics. Hence in this paper the condition of the "best" design are both defined and fulfilled in the
framework of thermodynamic arguments, which we believe has profound consequences for the designs of thermal and
even photovoltaic systems, even illumination and optical communication tasks. This new way of looking at the
problem of efficient concentration depends on probabilities, geometric flux field and radiative heat transfer while
“optics” in the conventional sense recedes into the background. Some of the new development of flow line designs
will be introduced and the connection between the thermodynamics and flow line design will be officially formulated
in the framework of geometric flux field. A new way of using geometric flux to design nonimaging optics will be
introduced. And finally, we discuss the possibility of 3D ideal nonimaing optics.
