Zone plates with 100 nm and 50 nm outermost zone width have now been fabricated with this method.
The zone plates have an outermost zone width of 80 nm, Ta thicknesses between 200 and 300 nm, and diameters between 250 and 500 μm.
It greatly increases the outermost zone width without changing the F-number, which brings a lot of benefits to the design and processing of diffraction device.
A mathematical model between geometrical concentration ratio, reflection times and the corresponding parameters is established, where the corresponding parameters include the parabola coefficient, outermost collector width, collector height, the expanding angle and the collector quantity.
One is a 5 mm zone plate with a resolution of 400 nm and the other is a matrix (30 × 30) different Zone Plates, each one 300 μm in diameter, with an outermost zone width of 1 micron.
The lateral resolution of XDM is ideally 60 nm and limited by the outermost zone width of the FZP.
A Fresnel zone plate with an outermost zone width of 25 nm was used to focus the X-rays onto the Fe@TiO2 nanoparticles on the TEM grids.
The outermost zone width correlates to the spatial resolution of the TXM image, so we can infer from above equation that decreased spatial resolution and shorter wavelength (harder X-rays) will increase the DOF.
A Fresnel zone plate (ZP) with an outermost zone width of 25 nm was used to focus the X-rays onto the ZnO nanorods on the transmission electron microscopy (TEM) grids.
Unavailability of separate bicycle paths, shrinkage of outermost lane width due to high roadside commercial and parking activities, and poor quality of pavement surface altogether have made these segment to offer poor and very poor services to bicyclists.
The objective lens is a Fresnel zone plate (FZP) with 60 nm outermost zone width, that projects the image onto a sCMOS camera with a pixel size of 6.5 μm (Neo 5.5, Andor) that can be operated up to 100 frames per second (i.e., 100 Hz).
