Title: Use of a focusing vortex lens as the objective in spiral phase contrast microscopy

Abstract

A method and objective apparatus are provided for implementing an enhanced phase contrast microscope. A focusing vortex lens, defined by a diffractive spiral zone plate (SZP) lens, is used for the objective for the phase contrast microscope. The SZP lens focuses and imparts a helical phase to incident illumination to image the specimen with spiral phase contrast. The spiral phase contrast microscope is sensitive to phase gradients in all sample axes. Replacing the objective of a microscope with the diffractive SZP lens of the invention immediately provides existing instruments with spiral phase contrast capability.
