To avoid direct radiation from neutrons, the CCD is coupled to the array by a mirror and lens optics.

CCD与光纤阵列之间采用反射镜和透镜耦合方式，使CCD避开中子源直接辐照。

In addition, providing the tools for manufacturable GRIN optics will expand the reach of GRIN lens design and fabrication methods beyond current optics application space.

此外，M - GRIN将使GRIN透镜的设计制造超越现有的光学应用范围。

To beam power from a Dyson-Harrop satellite to Earth, one "would require stupendously huge optics, such as a virtually perfect lens between maybe 10 to 100 kilometres across," he says.

为了将能量从Dyson-Harrop卫星送回地球“需要奇大无比的透镜，比如10公里到100公里范围的完美透镜。”
