An exceptional component offered by Knight Optical – the leading supplier in high-quality, metrology-tested optics – is the Fresnel Lens; popular for a range of uses, from integration with traffic ...

Diffractive deep neural networks (D 2 NNs) are optical systems composed of successive transmissive layers optimized through deep learning to perform computational tasks in an all-optical manner. The ...

A British nanotech invention has revolutionized the humble optical microscope by quadrupling its magnification power to a level far beyond what could previously be achieved with visible light. The new ...

A periscope camera lens is a lens assembly that uses prisms, mirrors, or a combination of them to redirect light before it reaches the camera sensor. In doing so, it magnifies the image more so than ...

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before ...

Smartphone accessories specialist Sandmarc has unveiled what it says is the first add-on telephoto lens designed specifically to mount on iPhone's periscope-style tetraprism camera, rather than the ...

IF N,u,η are the refractive index, the paraxial angle, and the size of object respectively, and dashes denote these quantities in the image space, then the magnification formula, is valid for ...

Apple has been researching how to make it simple for a future iPhone user to directly see the difference between Wide and Ultra Wide lenses, giving experienced users more control. The odds are that ...

Concentrated photovoltaics (CPV) is an application which generates electricity from sunlight. The key difference between this technology and conventional photovoltaics (solar panels) is the inclusion ...
