In this study, we design a Cassegrain-based concentrator with tailored mirrors. The proposed concentrator comprises a primary optical element (POE) and a secondary optical element (SOE). The POE is a parabolic concave mirror and the SOE is a hyperbolic convex mirror. In order to achieve uniform irradiance distribution without a homogenizer, the POE is tailored and tilted to generate a uniform distribution by overlapping the energy well. The Cassegrain-based concentrator with tailored mirrors can achieve a geometric concentration ratio of 1236×, a concentration ratio of 1034×, an optical efficiency of 83.66%, an acceptance angle of ±0.38, a uniformity of 7.87, and an aspect ratio of 0.254.
在本研究中，我们设计了一种带有定制反射镜的卡塞格伦聚光器。所提出的聚光器包括一个主光学元件（POE）和一个次光学元件（SOE）。主光学元件是一个抛物面凹面镜，次光学元件是一个双曲面凸面镜。为了在不使用均化器的情况下实现均匀的辐照度分布，对主光学元件进行了定制和倾斜，以便通过能量阱重叠来产生均匀分布。带有定制反射镜的卡塞格伦聚光器可实现1236倍的几何聚光比、1034倍的聚光比、83.66%的光学效率、±0.38的接收角、7.87的均匀性以及0.254的长宽比。
