Diffraction is often touted as an image killer, and people talk about the "diffraction limit" as the point at which you can no longer resolve an image "usefully". On the contrary, the diffraction limit is only the point where diffraction starts to affect an image for the particular image m...

polymerization, while researchers at the University of Maryland (Science doi: 10.1126/science.1168996; 2009) used two lasers — one continuous and one pulsed — operating at a wavelength of 800 nm to produce feature sizes as small as 40 nm, which is a factor of 20 less than the wavelength...
What is the diffraction limit? From Airy to Abbe using direct numerical integration. The resolution of a conventional optical microscope is sometimes taken from Airy's point spread function (PSF), 0 . 61 λ / NA , and sometimes from Abbe, λ / 2 NA , where NA is the numerical aperture...

aNear-fieldmicroscopy offers the opportunity to reveal optical contrast at deep subwavelength scales. In scanning near-field optical microscopy (SNOM), the diffraction limit is overcome by a nanoscopic probe in close proximity to the sample. The interaction of the probe with the sample fields necessa...
The materials characterization process helps you choose the best materials and design — and discover the root causes of any product failures.
The Modulation Transfer Function (MTF) is a performance metric that measures the degradation of contrast in the image compared to contrast in the object. There are several factors that cause contrast degradation, such as diffraction effects, optical aber
