NASA's James Webb Space Telescope is the largest and most powerful telescope ever launched to space. Its mirror is composed of 18 individual segments that have been aligned so accurately, that they ...

Researchers in Canada have built the first deformable liquid mirror from a magnetic liquid or “ferrofluid”, which could someday be used to compensate for distortion in the images of telescopes and ...

Ball Aerospace is celebrating today’s launch of NASA’s James Webb Space Telescope (Webb) from French Guiana. The Colorado-based company designed and built the advanced optical technology and ...

In a kaleidoscope, mirrors are placed at angles to create a visual illusion of multiple, symmetric images from one original object. The number of symmetric axes in the kaleidoscope depends on the ...

As frustrating as having an atmosphere can be for physicists, it’s just as bad for astronomers, who have to deal with clouds, atmospheric absorption of certain wavelengths, and other irritations. One ...

LetinAR, a Korea-based startup developing optical solutions for AR headsets and smartglasses, showed off a new implementation of their ‘pin mirror’ optical tech at Mobile World Congress (MWC) this ...

Researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Faculty of Arts and Sciences have devised a new way to make some of the smallest, smoothest mirrors ...

Cutting-edge hard X-ray microscopy strongly depends on sophisticated focusing optics and ultrabright X-ray sources at synchrotron-radiation and X-ray free-electron laser (XFEL) facilities. These ...

Japanese technology giant Mitsubishi Electric says it has developed a compact lidar system aimed at use in future autonomous vehicles. The Tokyo firm claims that its selection of an optical MEMS-based ...

Many optical systems include mirrors as a component. They are used to direct and focus light, combine wavelengths, and reject specific wavelengths in imaging and a host of other applications. Multiple ...
