Beating the Diffraction Limit When they pass through a hole or past a material edge, light waves will diffract--that is,
This diffraction will limit the sharpness of any imaging performed by the light. Indeed, this diffraction limitation is one of the traditional features of classical optical science dating back to the mid 19th century.
What this principle says is that in using light with a certain wavelength (denoted by the Greek letter lambda) an object can in general be imaged with a spatial resolution roughly no finer than lambda.
The advent of quantum optics and the use of"nonclassical light"dodged the diffraction limit.

Diffraction limittraditional microscopy is limited by the diffraction of light around objects. That is when a light wave from the source strikes the object, the wave will scatter somewhat.
