    |<

    0.5 where φ

    x is power of an axis perpendicular to a direction of decentering of the deformable reflecting surface;

    φ

    y is power of an axis in parallel with a direction of decentering of the deformable reflecting surface; and

    φ

    is power of an entire optical system.
