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

It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

To serve remote areas of the world, doctors, nurses and field workers need equipment that is portable, versatile, and relatively inexpensive. Now researchers have built a compact, light-weight, ...

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 ...

On a late night in February 2011, two Princeton University researchers packed a small object into a box and set it out for the morning mail. The engineers had spent four years developing a new type of ...

Engineers from Ohio State University have developed what they say is the world's first microscope lens capable of obtaining three-dimensional images. While 3D microscopy has already been achieved, it ...

Researchers from the University of Houston have created an optical lens that can be placed on smartphone to magnify images and provide schools and clinics a low-cost alternative to the conventional ...

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 ...

Instead of lugging a heavy microscope into the field, doctors and nurses in remote regions may have a more portable choice -- a lightweight microscope that replaces lenses with holograms. Researchers ...
