The wave nature of light limits the size of the spot to which light can be focused due to the diffraction limit. This limitation was described in the 19th century by Ernst Abbe and "limits an optical microscope's resolution to approximately half of the wavelength of the light used." Fluorescence microscopy is central to many techniques which aim to reach past this limit by specialized optical configurations. WebEpi-Fluorescence. The world of fluorescence microscopy involves illuminating a sample specimen under controlled conditions and then observing how that sample both absorbs …
