It arises due to the wave nature of light and the physical limitations of focusing light through a lens system. The diffraction limit restricts the spatial resolution of optical microscopes, making it ...

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 ...

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 ...

microscope uses a pulsed infrared laser to stimulate fluorescence excitation only with the diffraction limited spot of the objective lens, thus creating an inherent optical section. The advantage of ...

The robots can mechanically adjust diffracting elements to enhance imaging, serving as diffraction gratings or integrating diffractive lenses. Acting as extensions of microscope lenses ...

We will cover the following areas: (a) Near Field Imaging: Field propagation, Diffraction ... Perfect lens, Meta-materials, Nano-antennas, Metal plasmon resonance; (c) Nanoscale Waveguide Based ...
