Refractive index measurement is at the heart of optical science, influencing everything from lens design to material characterization. Modern techniques span from classical prism-based methods to ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

Toyohashi University of Technology researchers in collaboration with Massachusetts Institute of Technology (MIT), have developed a new material capable of retaining high transmissivity after thermal ...

We all look in the mirror at least once a day to see our reflection. Mirrors are used not only in daily life but also in cutting-edge technologies such as semiconductor processing and high-resolution ...

A team of scientists has uncovered a crystal that can be reshaped and programmed using ordinary light, opening a new path for ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Researchers at Kyushu University have developed SeeDB-Live, a method that temporarily makes living brain tissue transparent ...
