Researchers at AIST have developed a device that measures the absolute surface profile of curved optical elements with high ...

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 ...

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 ...

Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass. Product specifications ...

French firm CILAS, which specializes in lasers and photonics technologies for military and astronomy applications, has signed an agreement to make some critical optical components for the Thirty Meter ...

A new optical prescription for automobile side-view mirrors may eliminate the dreaded "blind spot" in traffic without distorting the perceived distance of cars approaching from behind. Objects viewed ...
