Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

a, An axi-symmetric binary phase filter (BPF) and image reconstruction network are jointly learned through the physics-informed neural network. The learned BPF is fabricated and inserted in a pupil ...

Light microscopes based on scattering, reflection and absorption, or a combination of these, have been a key enabling technology for the study of objects invisible to our eyes, especially in the field ...

Zooming in: image of mouse embryo. (Courtesy: Gail McConnell/University of Strathclyde) A new microscope lens that offers the unique combination of a large field of view with high resolution has been ...

Scientists have developed the first flat lens for immersion microscopy. This lens, which can be designed for any liquid, may provide a cost-effective and easy-to-manufacture alternative to the ...

The little picture: Microscopes are cool. There is something fascinating about looking at objects that you cannot normally see with your naked eye. Of course, carrying a microscope around for whenever ...

Researchers have developed a novel low-cost, compact, portable on-chip light microscope capable of carrying out ultrasensitive analysis of transparent objects and biomarkers in a large detection ...
