Формула изобретени Invention Formula Компенсатор аберраций дл  контрол  асферических зеркал, содержащий два плосковыпуклых компонента, установленных между контролируемой поверхностью и ее центром кривизны, отличающийс  тем, что, с целью уменьшени  чувствительности к децентрировке , компонент, расположенный со стороны центра кривизны контролируемой поверхности , выполнен склеенным из дво ковыпуклой и плосковогнутой линз и обращен плоской поверхностью к второму компоненту, при этом рассто ние между двусклеенным и одиночным компонентами выбрано равным 0,25-0,4 рассто ни  от центра кривизны контролируемой поверхности до одиночного компонента, разность показателей преломлени  стекол плосковогнутой и дво ковыпуклой линз выбрана больше 0,09, а отношение радиусов кривизны поверхностей дво ковыпуклой линзы, граничащих соответственно с воздухом и стеклом, выбрано в пределах 3,5-4,5.An aberration compensator for controlling aspherical mirrors, containing two plane-convex components installed between the test surface and its center of curvature, characterized in that, in order to reduce the sensitivity to decentration, the component located on the center of curvature of the test surface is glued together from two-convex and flat-concave lenses and facing a flat surface to the second component, while the distance between the twin-joint and single components is chosen equal to 0.25-0.4 distance from the center of curvature of the test surface to a single component, the difference in the refractive indices of flat-curved and two-convex lenses is chosen to be more than 0.09, and the ratio of the radii of curvature of the surfaces of two-convex lenses bordering air and glass, respectively, is between 3.5 and 4.5 .
