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

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 ...

The optical microscope relies on light and consists of two main lenses: • The objective lens, which magnifies the object you wish to observe (with various magnification options). • The eyepiece, which ...

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 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 ...

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the ...

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 ...
