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 ...

UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional ...

Researchers have created an optical lens that can be placed on an inexpensive smartphone to magnify images by a magnitude of 120, all for just 3 cents a lens. Researchers at the University of Houston ...

A British nanotech invention has revolutionized the humble optical microscope by quadrupling its magnification power to a level far beyond what could previously be achieved with visible light. The new ...

recording condition for three angles, 50°, 0°, and −50°, respectively. (B1–B3) Cropped images from corresponding superresolved holograms of 5 μm beads (at z ¼ ∼0.8 mm) measured at illumination angles ...

The techniques used in optical microscopy are important to ensure that a sample can be viewed as clearly as possible. This will provide information about its microscopic appearance. An optical ...

Researchers in Australia have invented a new kind of optical lens that could be combined with a smartphone camera to create a microscope for diagnosing skin cancer or identifying agricultural pests.

A new generation of optical lenses is being developed and tested at multiple universities and companies worldwide. These lenses, known as metalenses, are silicon films a thousand times thinner than a ...

Researchers have redesigned the concept of a microscope, by removing the lens, to create a system small enough to fit in the palm of a hand, but powerful enough to create 3-D tomographic, or sectional ...
