Extreme Ultraviolet Beams Gets Its First Atomic Jet Lens

The Max Born Institute (MBI) scientists have created the first of its kind refractive lens that aims extreme ultraviolet beams. The researchers have used a jet of atoms to form a specific lens instead of the traditional non-transparent glass lens in the extreme-ultraviolet region. This probably can help reduce the timescales for the imaging of biological samples.

The refraction is a concept followed not only in the cases of the bending of trees in the direction of light but also in our daily lives such as contact lenses, glasses, certain laser beams, and camera objectives. The refractive lenses were created consecutively after the identification of the new electromagnetic spectrum region such as ultraviolet (UV) and X-ray radiation. The extreme-ultraviolet (XUV) region is a special wavelength range amid the UV and X-ray electromagnetic radiation domain with extremely different properties like it can only travel via strongly rarefied gases or vacuum. In the present day, the XUV beams have a number of applications in the fundamental research plus semiconductor lithography in order to value the dynamics or control the structures of distinct matters. The shortest manmade light pulses with attosecond intervals can also benefit from it. The XUV radiations tend to absorb into the liquid or solid materials hence, its applications or sources have not yet been brought into existence.

The new approach taken by MBI researchers to focus on the XUV beams and also the use of a jet of atoms made of helium will help transmit faster as well as gain control by altering the concentration of the gas in the jet. This, in turn, will aid in adjusting the focal length plus reducing the target sizes of the focused XUV beams. The gaseous refractive lenses help create new lenses by significantly changing atom flows and avoid the damages expected in the curved mirrors. The XUV beams are not only expensive but also complex. The atomic jet works a prism by scattering the XUV radiation into its constituent spectral components. The spectral colors of the XUV light are generally not visible to the naked eyes. This can be used for developing XUV microscope, to focus XUV beams to nanometer speck sizes, or even observing biomolecules structural changes within a small time. A team at the Center for Research on Redox Processes in Biomedicine have found that the visible lights reaction on the skin despite the sunscreen protection accounts to skin cancers. The group has patented skin-colored sunscreen that can block visible light.
