Abstract:
1. An optical system for correcting optical aberrations, the optical system comprising: a dome, through which an optical wavefront can pass, comprising a spherical portion and a non-spherical portion, wherein the non-spherical portion is coupled to the spherical portion and the non-spherical portion has circular curvature along a first axis; a lens configured to provide circular curvature to an optical wavefront incident upon the non-spherical portion normal to the first axis, and a mount coupled to the lens and configured to move the lens parallel to the first axis between a first and second position, in the first position the lens intersecting a radial path from the first axis to the non-spherical portion to alter wavefronts of light passing through the non-spherical portion of the dome toward the first axis, and in the second position being outside of the radial path; wherein wavefronts of light having passed through the spherical portion of the dome will be spherically shaped and wavefronts of light having passed through the non-spherical portion of the dome and the lens along the radial path will be spherically shaped.
