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 ...

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 ...

A project at the University of Zurich has designed an objective for light microscopy based on the reflective principles used in Schmidt telescopes and also found in nature in the eyes of scallops. The ...
