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

-Sapphire glass has a large dispersion, which means that light of different wavelengths will experience significant ...

Flat lenses, designed using advanced lithography techniques ... Curved mirrors, although lighter, can introduce distortions and chromatic aberrations, compromising image quality. Diffractive lenses, ...

Here's how an innovative flat lens could solve these problems for satellites and space-based telescopes. Understanding ...

The authors propose to mitigate these aberrations by designing and fabricating aspherical corrective lenses using ray trace simulations and two-photon lithography, respectively; the corrective lenses ...

High-NA EUV makes progress toward high-volume manufacturing while optical lithography sees continued advances.

Many conclude from this that China could soon be producing chips using highly complex extreme ultraviolet (EUV) lithography technology. This would be a huge success for the country, as so far only ...
