Engineers at UC Berkeley have created a new high-performance mirror that packs the same 99.9 percent reflective punch as current high-grade mirrors, but in a package that is 20 times thinner and ...

Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e ...

A good rifle scope maintains optical clarity, minimizes parallax, is non-reflective and is resistant to moisture, dirt and mechanical shock. These scopes must also be suitable in a wide variety of ...

A high reflectivity mirror, also known as a supermirror, is a dielectric mirror that has been carefully designed to provide optimal reflectivity while minimizing any scatter and absorption effects.

A focused beam of green light has transformed 150 plastic beads into a functional mirror. The feat is the first step toward an ambitious goal: deploying lasers in space to assemble a cloud of dustlike ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250274 .Tunable lasers are key light sources capable of precisely ...

Wavelength separation or combination can most easily be achieved by mirrors with special dichroic coatings. Application examples include the input of pump radiation to solid state lasers, the ...

Berkeley — Engineers at the University of California, Berkeley, have created a new high-performance mirror that could dramatically improve the design and efficiency of the next generation of devices ...
