In conventional lenses, the imaging is limited by the diffraction limit.

This compares with λ/2, from normal diffraction limit for conventional lenses.

In practice the lowest value of "d" obtainable with conventional lenses is about 200 nm.

This requires specialized optical equipment, which is also limited because these use the conventional lens.

Furthermore, conventional lenses capture only the propagating light waves.

Like a conventional lens, the z-direction is along the axis of the roll.

The performance limitation of conventional lenses is due to the diffraction limit.

The Cyclops used a conventional lens to focus an image on the sensor array.

If there is only one such zone, it is a conventional lens.

This would require a very thick and heavy lens if a conventional lens were used.
