A common aberration with water-immersion objective lenses.
We describe here an aberration that is frequently encountered with water-immersion but not oil-immersion objectives. The aberration is shown to be induced by tilt of the coverslip out of the plane normal to the optical axis. Model calculations taking into account the path-length distortions introduced by a tilted coverslip satisfactorily reproduce the observed effect on the images of small subresolution fluorescent beads.
