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 ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Scientists from the UK and China have developed a lateral-graded multilayer grating that addresses a key challenge in tender ...

Researchers in Switzerland have made a popular materials characterization technique accessible to ultrafast X-ray laser light for the first time. The new approach allowed the team to film atomic ...

Figure 2: Influence of membrane thickness and material composition on the van der Waals interaction in molecule diffraction. The central result of our diffraction experiments is the observation of ...

Holographic and Ruled diffraction gratings are available from Optometrics for use in high-level spectroscopy, alongside our Echelle, Filtered and Transmission gratings. One of the few gratings ...

Physicists from MIPT and University Jean Monnet (France) have developed a new simulation method for optical elements used in many modern instruments and devices. Their paper, presenting a description ...

There was a question from Jerry in a previous post: "A simple question for which I can't find an answer: Why do you have to collimate light spectroscopy? What would happen if you didn't collimate it?" ...
