FIELD: physics.
SUBSTANCE: invention can be used to control the shape of large-size concave aspherical optical surfaces with high steepness and asphericity gradient, both monolithic and composite aspherical mirrors and lenses. Axial synthesized holographic optical element comprises a substrate with a working optical surface of rotation, made in the form of a circular cone, on which a coaxial annular diffraction structure is applied, which is a system of concentric alternating reflecting and non-reflecting rings.
EFFECT: technical result is reduction of dimensions of axial synthesized holographic optical element due to use of diffraction structure providing compensation of longitudinal spherical aberrations of normals to controlled surface or light beams reflected from it.
