Abbe Diffraction Limit

The Abbe Diffraction Limit is a fundamental principle in optics that defines the smallest detail a microscope can clearly resolve. It occurs because light waves bend and spread when passing through tiny openings or around objects, which creates a limit to how finely we can distinguish two close points. Essentially, if two objects are closer together than this limit, they will appear as a single blurred spot. This limit depends on the wavelength of light used and the quality of the optical system; shorter wavelengths and better optics allow for higher resolution and finer detail detection.
