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

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 ...

The demand for disposable miniature imaging platforms (DMIPs) is growing rapidly. Used for commercial, scientific, medical, and educational purposes, DMIPs have numerous applications but can be ...

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 ...

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 ...

“It’s a low cost and easy lens-making recipe,” Lee says. The researchers made lenses about a few millimeters thick with a magnification power of 160 times and a resolution of about 4 microns ...

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.

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before ...
