本文介绍了一个二向色镜的设计，制造和测试，将在深空天线的欧洲航天局在澳大利亚的珀斯。分色镜设计用于在35 m反射器天线的波束波导馈电系统中组合S和X波段的信号。最终的设计包括一个直径为2.5米的厚金属板，周期性地穿有圆形十字形孔。这种结构的设计需要在电气、机械和技术限制之间进行权衡。验证样品的设计和测试，以及最终的镜子进行了讨论。
The paper presents the design, fabrication, and testing of a dichroic mirror to be operated in the deep-space antenna of the European Space Agency in Perth, Australia. The dichroic mirror is designed for combining the signals in the S and X bands in the beam-waveguide feeding system of the 35 m reflector antenna. The final design consists of a thick metal plate of 2.5 m in diameter, perforated periodically with rounded cross-shaped holes. The design of such a structure required a trade off between electrical, mechanical, and technological constraints. The design and testing of a validation sample as well as of the final mirror are discussed.
