Abstract

The shape of axisymmetric mirrors capable of producing a constant concentrated flux density along a coaxial cylindrical surface is determined via both a series solution and a phase plane analysis of the governing second-order nonlinear differential equation. It is shown that there exists a class of such concentrators and that they all have a characteristic bell shape with two finite principal radii of curvature. Mirrors of this type may find application in processes requiring concentrated uniform illumination over extended areas such as in photovoltaic energy conversion.
