As the pattern is transferred, it is reduced in scale by a projection lens ... ultraviolet lithography can achieve these resolutions with a single exposure and with fewer design restrictions ...

Photolithography at a wavelength of 193 nm in the deep UV with water immersion lenses can now produce microelectronics containing features with a half-pitch as small as 40 nm. The big question is ...

Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

Lenses have always worked by bending ... galaxy that is outshining stars Using a novel computational design method and ...
