This meant that a microscope could not resolve two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens. This diffraction ...

Advancements in Optical Lenses: Simplified FZP Fabrication ProcessResearchers introduce a cost-effective method for producing optical Fresnel zone plate lenses, using colored photoresists for ...
Of course, lenses and diffraction gratings are relatively simple. You need real data, and for this we can turn to another one of [esben]’s projects in the Hackaday Prize. It’s a breakout ...
Recent research has focused on various types of DOEs, including Fresnel lenses, diffraction gratings, and specialized designs like the lobster eye telescope, which are tailored for specific ...
Wikipedia says that "diffraction occurs when light hits an opaque edge in the light path, such as the aperture blades in the lens. Diffraction causes the light to be spread out in a plane that is ...
The term "diffractive robotics" reflects the groundbreaking integration of untethered robotic movement with light diffraction ... the precision of a microscope lens directly at the nanoscale.
