罗马任务完成关键光学元件

罗马任务完成关键光学元件

Ball Aerospace 的工程师是 NASA 南希格雷斯罗马太空望远镜的工业合作伙伴之一,他们已经将元件轮组件(如上图所示)安装并对准到望远镜的广角仪器中。该组件包含八个科学过滤器、两个色散元件(棱镜和棱镜)和一个“空白”元件(用于内部校准),这将帮助科学家在 2027 年 5 月罗马发射时解开天体物理学中一些最深刻的谜团。


光线经过罗曼的主副镜反射聚焦后,会通过元素轮。聚焦和过滤的光然后将到达一个大型检测器阵列,在那里创建图像。根据研究人员正在寻找的东西,科学过滤器将允许天文学家选择特定波长的光进行观察。棱镜和棱镜是用于光谱学的工具,旨在将来自宇宙物体的光分散成不同的颜色。这些彩虹般的测量,称为光谱,包含有关来源的独特签名,这些签名提供有关其性质的线索。例如,天文学家将能够测量数以千计的整个星系如何在太空中移动,这将帮助他们了解宇宙在不同时间点的膨胀速度。这样做可以帮助确定暗能量的性质——加速宇宙膨胀的神秘宇宙压力。

棱镜和棱镜由 Optimax、Jenoptik 和 NASA 的戈达德太空飞行中心制造和测试,以确保它们满足 Roman 的严格要求。该团队在低温真空容器中模拟了类似太空的条件,将温度降低到大约负 190 华氏度(负 123 摄氏度)。由于大多数材料在加热时会膨胀,在冷却时会压缩,因此工程师必须确认光学器件能够在 Roman 的超冷工作温度下按计划工作。棱镜和棱镜都通过了,测试图像显示出最小的失真。天文学家将使用这些组件来探索宇宙中一些最大的谜团。
