Using a wider aperture to stay below the diffraction limit.
In conventional lenses, the imaging is limited by the diffraction limit.
The performance limitation of conventional lenses is due to the diffraction limit.
One does not so much "break" as "run around" the diffraction limit.
One way to get around the diffraction limit is to stick a tiny light source very close to the sample.
But in space, or if adaptive optics are used, then reaching the diffraction limit is sometimes possible.
Like, at least a sentence explaining what the hell a diffraction limit actually is.
This diffraction limit is based on the wave nature of light.
This is far below the diffraction limit ( 200 nm).
The diffraction limit is only valid in the far field.
