Every lens has a sweet spot, the aperture where the image sharpness is at its best. If the aperture becomes larger, lens errors will become visible. When the aperture is closed, lens diffraction will ...

When browsing social media or the internet, one occasionally encounters theoretical discussions about 'lens resolution ...

If you are like me then you might not always get caught up in some of the super technical aspects of photography. One aspect of photography I recently investigated was the loss of sharpness caused by ...

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...

I feel like the photos I used to see in large-format magazines back in the day had a sharpness comparable to what you get ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

Flat lenses offer a way to minimize the optical aberrations and astigmatisms that conventional spherical lenses can be prone to, and can potentially open up new applications that traditional lens are ...

Newswise — To design and improve energy storage materials, smart devices, and many more technologies, researchers need to understand their hidden structure and chemistry. Advanced research techniques, ...

Diffractive optical lenses are special lenses that function based on the principle of diffraction. Like normal, traditional lenses, diffractive optical lenses also focus the input light beams onto a ...

Edmund Optics' TECHSPEC MWIR (midwave infrared) achromaticlenses can be used by designers and researchers working in the 3-µm to 5-µmspectral region. Providing near-diffraction-limited performance, ...
