Microscope lenses are typically made either by grinding and polishing glass discs, or pouring polymers into molds – both techniques can be quite involved, which is reflected in the price of the ...

Contact lenses represent one of the single largest categories of medical devices, with more than 31 million contact lens wearers in the United States alone, according to the Association of Contact ...

A tiny, disposable lens that costs a few pennies to produce could soon begin turning smartphones into a powerful microscope that scientists, engineers and even schoolchildren can use almost anywhere.

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 ...

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 ...

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 ...

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.

This electron microscope image shows the structure of the lens (white line is 0.002mm long) A flat lens made of paint whitener on a sliver of glass could revolutionise optics, according to its US ...

While financial contributions are certainly a great help to health care practitioners in developing nations, one of the things that they really need is rugged, portable, low-cost medical equipment ...

Researchers have come up with a microscopic microscope, tiny enough to fit on a fingertip, that can be cheaply mass-produced and used to scan blood and water for pathogens. The high-resolution ...

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 ...
