Scientists Using 3D Printing Technology Made The Nanoscale X-ray Lens
Oct 17, 2018

The Max Planck Institute of Intelligent system of Stuttgart (Max Planck Institute for Intelligent Systems for Stuttgart) scientists using 3D printing technology, with nanoscale characteristics and remarkable ability to focus the polymeric material made the X-ray lens.The new technique enables them to within a minute to create each lens with excellent x ray optical properties, thus reducing the cost of prototyping and manufacturing.Scientists have applied for a patent for their invention.

   An overview of the manufacturing methods, micrograph by scanning electron microscope (sem)                                                                                 imaging.

X-ray microscope is uniquely combined with nanoscale resolution and large penetration depth imaging tools.X-ray microscopy (XRM or is the only technology to study buried by high resolution characteristics, for example, it allows you to without destroying the computer's central processing unit under the condition of view of the defect, the micro mechanical visible under the working conditions, and the study of natural environment cell organelles.

However, focusing on X-ray needs to be very challenging nano optical geometry.Due to its complex nano manufacturing method, the cost of one camera up to tens of thousands of euros.

Located in Stuttgart, Max Planck institute of intelligent system of modern magnetic system and the physical intelligence departments, to find a new, cheaper to make the 3D motion model method, the polymerization can effectively focusing X-ray lens.Under the approximate model of non-ideal sports forming step requires more complex manufacturing process.This is the place where 3D printing function.They found that femtosecond two-photon 3D nano etching is the best way to make them x diffraction optical.

"We use femtosecond pulse infrared (IR) laser and a photoresist, can absorb more infrared photons aggregated at the same time, the structure is smaller than the wavelength of light," said Umut t. Sanli explained that he is a modern system of micro/nano magnetic optical group of doctoral students."In this way, we implemented a challenging X-ray lens geometry structure, has the characteristics of nanometer size and focus on efficiency is very high," he continued.Preliminary results show that the direct soft X-ray imaging and 3D printing of ptychography action form shows excellent performance, efficiency is as high as 20%.
