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

Scientists have developed the first flat lens for immersion microscopy. This lens, which can be designed for any liquid, may provide a cost-effective and easy-to-manufacture alternative to the ...

Researchers have proposed a new method to form an electron lens that will help reduce installation costs for electron microscopes with atomic resolution, proliferating their use. Instead of the ...
