A nanofabricated silicon template holds two independent multilayer Laue lenses with high precision for easy alignment to create a nano-focused X-ray beam. Scientists have developed a new type of lens ...

Increasing demands on the performance of optical systems require tighter mechanical and optical tolerances. Thus, it has become unfeasible – both technologically as well as financially – to manually ...

A new fortuitous alignment has allowed a cluster of galaxies to play a crucial role. Nicknamed the “carousel lens,” this unique gravitational lens reveals not one, but seven distant galaxies.

Gravitational lensing, predicted by Einstein's theory of relativity, involves the bending of light from a distant object (e.g., a quasar) by a closer, massive object (e.g., a galaxy), acting as a lens ...

‘Collimating’ refers to the process of accurately aligning light or particles in a parallel manner. When used in light measurement applications, collimating ensures that the propagating light exhibits ...

Increasing demands on the performance of optical systems require tighter mechanical and optical tolerances. Thus, it has become unfeasible – both technologically as well as financially – to manually ...

Scientists have developed a new type of lens that focuses an X-ray beam to nanometer levels. This is a scale smaller than a single virus. The monolithic 2-D multilayer Laue lenses (MLLs) can focus an ...
