Carving diamonds for optical components

Thanks to a new technique developed at EPFL, optical diffraction gratings can now be made out of pure diamond, with their surfaces smoothed down to the very last atom. These new devices can be used to alter the wavelength ...

Webcams offer a low-cost way to tune lasers for serious science

Every photon in a laser beam marches in lockstep, at an identical wavelength that depends on what the laser is used for – for example, infrared lasers that drive the optic fiber internet. For many applications, lasers need ...

Scientists proposed a novel configuration of nanoscopes

Scientists from Tomsk Polytechnic University together with colleagues proposed using special diffraction gratings with gold plates instead of microlenses used in the classic configuration to obtain images in nanoscopes. Microlenses ...

Measure greenhouse gases from space

Space agencies examine the extent of greenhouse gases in the air via prisms and gratings in satellites. New technology now makes it possible to connect both components with each other so that they are suitable for space thus ...
