In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a ...

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.

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 ...

Follow the build process of a custom microscope, from a simple single-lens macro setup to a more advanced three-lens configuration. This section highlights the use of 3D-printed parts, lens alignment, ...
