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 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 developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive 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 ...

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.
