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

Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

One of the best known properties of light is that it diffracts, bending or spreading around objects that lie in its path. A familiar example is when a collimated beam of light passes through a small ...

An unexpected discovery in a Harvard lab has led to a breakthrough insight into choosing an unconventional material, silica, ...

Joost van Mameren explains how quantitative force measurements by optical tweezers can unravel the mechanical properties of biological molecules 1 Forces at work in optical tweezers Qualitative ...

As phones, computers and other electronics have grown ever smaller, their optical components have stubbornly refused to shrink. Notably, it is hard to make tiny lenses with traditional glass-cutting ...

A career in optical physics or engineering means knowing about the behavior and properties of light, including its interactions with matter and its detection by instruments. Since the discovery that ...

Biconvex lenses also known as double convex lenses are simple optical lenses with two convex spherical surfaces, surfaces which bulge out from the center. These two convex surfaces have the same ...
