A continuous-wave laser study finds strong third-order nonlinear optical responses in MEH-PPV and PBDB-T polymer solutions, ...

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 ...

Researchers fabricated a 1200 lines/mm gold-coated pulse compression grating with 91.4 percent average diffraction efficiency ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

Spectrometers are crucial scientific instruments in various research fields and have consistently served as indispensable tools for foundational research. However, the unwieldy size of conventional ...

Difference between Interference and Diffraction: This article covers an important topic from Class 12 Physics. As we all know, Physics is one of the toughest subjects in Class 12. With the vast amount ...

Beauty is in the eye of the beholder, and when it comes to “sunbursts” in photos – those points of light with rays streaking out of them – people often have polarizing views. Optical diffraction is ...

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 ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
