Simple Methods to Approximate CPC Shape to Preserve Collection Efficiency

Figure 7

Comparison between simple power-approximation method (solid line) and corrected-power approximation method (dashed line). The lines refer to the normalized integral power incident on a small longitudinal section of the ideal CPC coplanar to the CPC axis (solid line) and to the same integral function after correction according to the corrected-power approximation method (dashed line).
