Using only a single-crystal piezoelectric thin wafer of lithium niobate (LN) instead of the usual two-part structure, a group from Nagoya University in Japan has created a deformable mirror that ...

Meta and Ray-Ban's AI-powered smart glasses remain surprisingly popular, while others have failed. Can you add prescription lenses to your pair?

Compared with a single lens, an achromatic doublet lens has much less spherical aberration. When used in an infinite conjugate state, their spherical aberration is minimal. Achromatic lenses are ...

Astronomers have constructed telescopes of every kind - massive observatories designed to pick up faint traces of light across space.

Ray-Ban took action from that line of thinking and attempted to, pun and all, reverse the less remarkable contributions of the eyewear industry as a whole. The Reverse collection offers acetate frames ...

Multibeam lens antennas are a potential future wireless communications technology. Finding the optimal feed position is necessary in multibeam applications. Focal region ray tracing is a highly ...

We also show that a pair of droplets connected by an EOF pump can function as a tunable convex lens system (TCLS). We developed a biocompatible and all polymer EOF micropump with an SU-8 substrate and ...

Snap rolled out a new feature for AR developers today: Ray tracing. The new tech allows devs to simulate light reflects on AR objects.
