Relationships that determine the design and size parameters of a two-mirror system are obtained on the basis of the development of a method for the construction and calculation (parametric synthesis) of optical systems composed of three reflecting surfaces. Possible versions of the construction of the fundamental layouts of three-mirror systems are considered. A relationship is obtained that determines the real value of the central-screening coefficient of an axial pencil of rays. It is shown that its value is determined by a fast primary mirror and in the limiting case can reach unity.
