Radius of petzval surface

WebA 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 Curvatureof the lens. Webof Petzval surface at a height y: • If the Petzval sum is zero then the lens has constant thickness across the aperture or across the field. • Compare with the image displacement S caused by a plano parallel plate: • The conclusion is that Petzval field curvature arises because the overall lens thickness variation across the
