Novel X-ray lens facilitates glimpse into the nanoworld | An achromatic X-ray lens
Scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just published by the researchers in the scientific journal Nature Communications.

Researchers have demonstrated a prototype glasses-free 3D light field display system with a significantly extended viewing distance thanks to a newly developed flat lens. The system is an important step toward compact, realistic-looking 3D displays that could be used for televisions, portable electronics and table-top devices.
