Researchers have shown how liquid crystals can be employed to create compound lenses similar to those found in nature. Taking advantage of the geometry in which these liquid crystals like to arrange ...

THE compound polarizer is a device for producing beams of polarized light of variable colours in the field of a microscope ocular. The polarizer proper consists of a disk of ‘Polaroid’, a disk of ...

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 ...

(Nanowerk News) The compound eyes found in insects and some sea creatures are marvels of evolution. There, thousands of lenses work together to provide sophisticated information without the need for a ...
