Paper Abstract

We developed a method of extending the depth of field of a microscope objective specifically used in an imaging system designed for small particle tracking. We extended the depth of field by inserting a quartic phase plate near the aperture stop plane of an objective. An optimum quartic phase plate was designed for a conventional 100X/0.8 microscope objective, and the simulation results predicated that the depth of field of the new objective could be increased more than twofold in comparison with an objective having no such phase plate.
