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

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

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

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 ...

In this study, we designed, developed and validated correction of optical aberrations in GRIN lenses of length 6.4 mm and 8.8 mm using a combination of ray-trace simulation, 3D microprinting by 2P ...

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