A simple lens focuses image points from an extended flattened object, such as a specimen on a microscope slide, onto a spherical surface resembling a curved bowl. The nominal curvature of this surface is the reciprocal of the lens radius and is referred to as the Petzval Curvature of the lens. Curvature of field in optical microscopy is a common and annoying aberration that is familiar to most experienced microscopists.
