5 DEVELOPMENTS AND MODIFICATIONS OF THE COMPOUND PARABOLIC CONCENTRATOR

5.1 INTRODUCTION

There are several possible ways in which the basic CPC as described in Chapter 4 could be varied for specific purposes. Some of these have been mentioned already, such as a solid dielectric CPC using total internal reflection. Others spring to mind fairly readily for specific purposes, such as collecting from a source at a finite distance rather than at infinity. In this chapter we describe these developments and discuss their properties.

5.2 THE DIELECTRIC-FILLED CPC WITH TOTAL INTERNAL REFLECTION

Both 2D and 3D CPCs filled with dielectric and using total internal reflection were described by Winston (1976a). If we consider either the 2D case or meridian ...
