Is it possible to magnify an object if the magnifier is sitting directly on top of the object (a focal length of zero)? How can this be accomplished if it is not possible with a traditional magnifier?

With atomic force magnification the object is very close to the magnifier..ksam said:Is it possible to magnify an object if the magnifier is sitting directly on top of the object (a focal length of zero)? How can this be accomplished if it is not possible with a traditional magnifier?
The focal length is the distance between the lens and the image sensor when an object is in focus. A focal length of zero means that the lens does not have any curvature and the focal point is located at infinity.
In theory, yes, it is possible to have a focal length of zero. However, in reality, it is not feasible as it would require a lens with infinite thickness and size.
A lens with a focal length of zero would not have any magnifying power as it does not bend or converge light. It would essentially act as a window, allowing light to pass through without any change in the size of the image.
No, current technology does not allow for a lens with a focal length of zero. The closest we can get is a lens with a very short focal length, such as a fisheye lens, but it will never be zero.
A lens with a focal length of zero could potentially be useful in certain types of imaging systems, such as microscopy or telescopes, where the focus is not necessary or desired. It could also be used in some specialized optical experiments and research studies.
