(Phys.org)—A widely-used tool for studying cellular structure – indeed, a technique in use throughout biology – phase contrast microscopy converts optical phase shifts to changes in brightness. At the same time, several ...
(PhysOrg.com) -- Conventional lenses can resolve structures around 200 nanometers (nm) in size, but scientists in Europe have for the first time developed a lens capable of achieving optical resolution of under 100 nm at ...
Transparent plastic optical lenses can be manufactured cheaply and in any shape. However, a downside is that they reflect light just as much as glass does. At the K trade fair in Düsseldorf, Fraunhofer researchers are exhibiting ...
