Aberration Invariant Imaging - Spherical AberrationImages of a bar target taken with a traditonal system under no aberration (left), with a traditional sysem with spherical aberration (middle), and with a aberration-invariant system with spherical aberration (right). Imaging with the standard system with this degree of spherical aberration results in a loss of contrast and a spatial resolution decrease of about a factor of two. Imaging with an aberration-invariant system under the same degree of spherical aberration results in no contrast loss and is nearly diffraction-limited. |
