Positioning of zone boundaries in this section. zone radii will be derived for a zone plate optic with focal length ff. Also. it’s equation resembles that of a lens. Improvements in the performance of such zone plates has recently led to some attention being given to their potential use as lenses in certain applications.

However. light through a lens undergoes refraction but light through a zone plate undergoes diffraction. In a final state. the thickness variation within every fresnel zone of the lens provides a phase shift from 0 to 360º.

#### Zone Plate As A Convex Lens.

The major advantages of such a fresnel lens are simple fabrication. large aperture size. polarization independent. and fast switching speed. although the required operating. The radial resolution of a zone plate is very close to that of a lens. Thus. the zone plate behaves like a convex lens with multiple foci.

#### In A Zone Plate. A Much Brighter Image Of An Object Is Obtained At The Screen. Which Shows The Converging Action Of A Zone Plate.

A zone plate of focal length 60 cm. behaves as a convex lens. if wavelength of incident light is 6000 a °. then radius of first half period zone will bea. What is a zone plate? In a zone plate. a much brighter image of an object is obtained at the screen. which shows the converging action of a zone plate.
