"WebAs was shown by Abbe over 100 years ago, the wave nature of light imposes a fundamental constraint on the attainable spatial resolution known as the “diffraction limit of light” (1). For commonly used dyes and high numerical aperture oil immersion objectives, this resolution limit is on the order of 250–300 nm. " - How does diffraction limit resolution

WebThe diffraction-limited resolution, often referred to as the cutoff frequency of a lens, is calculated using the lens f/# and the wavelength of light. Learn more about f/# in f/# … The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a principal limit to the resolution of any optical system, due to the physics of diffraction. An optical system with resolution performance at the instrument's theoretical limit is said to be diffraction-limited.

WebThe resolution predicted by the diffraction limit pertains to optimum conditions, including an unlimited signal-to-noise ratio. Fluorescence microscopy is limited in practice by low photon yield, and requires a ratio of excitation to emitted photons that typically ranges in the millions.
