The problem of the diffraction of electromagnetic waves by a circular aperture in an infinitely conducting planar screen is studied. Attention is focused chiefly on the low frequency end of the ...

Here, we report a versatile soft x-ray diffraction microscope with 70- to 90-nm resolution by using two different tabletop coherent soft x-ray sources-a soft x-ray laser and a high-harmonic source. We ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

Place the laser on top of the lab jacks, making sure the laser is pointed away from people. Place the slide mount on the optical rail and insert the sample slide to the slide mount. Plug in the laser ...

A: The resolution of an instrument that uses light to see things can’t improve beyond a point. This is called the diffraction limit. The resolving ability of, say, a telescope says how well it can ...

Fluorescence microscopy techniques are powerful tools for probing very small signals and revealing three-dimensional (3D) structural and functional properties of biological samples with high ...
