This paper proposes an optical system of the telescope for space research. The system comprises a segmented spherical mirror with a diameter of 10 m and a secondary aspherical mirror. The focal length of the telescope is equal to the radius of a spherical primary mirror. The paraxial focal point of the spherical mirror is aligned with the focal point of the whole system. The closest analog of the proposed optical system is the optical system of the Millimetron space observatory (Spektr-M). The physical aperture ratio of the proposed system is ten times that of the Millimetron telescope with the same overall dimensions. The proposed system rigorously satisfies the Abbe sine condition. The focal length of the system is 7070 mm, and the numerical aperture is 0.7071. The Airy disk diameter of the proposed system is more than ten times smaller than the diffraction circle of the Millimetron telescope. The angular field of the system is determined by the selected image quality criteria and specific wavelength.

直径为10 m的球面主反射镜的超快速非平面空间望远镜系统

本文提出了一种用于太空研究的望远镜光学系统。该系统包括一个直径为10 m的分段球面镜和一个辅助非球面镜。望远镜的焦距等于球面主镜的半径。球面镜的近轴焦点与整个系统的焦点对齐。拟议中的光学系统最接近的类似物是Millimetron空间天文台（Spektr-M）的光学系统。拟议系统的物理孔径比是具有相同总体尺寸的Millimetron望远镜的物理孔径比的十倍。拟议的系统严格满足阿贝正弦条件。该系统的焦距为7070毫米，数值孔径为0.7071。拟议系统的艾里斑直径比Millimetron望远镜的衍射圆小十倍以上。系统的角场由选定的图像质量标准和特定波长确定。
