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 ...

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 ...

Over on YouTube [Applied Science] shows us how to make an f/0.38 camera lens using an oil immersion microscope objective. The f-number of a lens indicates how well it will perform in low-light. To ...

Placing colloidal spheres in the immediate proximity of fluorescent molecules makes it possible to achieve single-molecule imaging at high temperatures with a low-cost system. In an optical microscope ...

A microscope objective lens produces a real, magnified image of an object placed within the field of view. Before it is observed the image is then magnified again by the ocular lens, also known as the ...
