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 ...

To measure the refractive index distribution in porcine eye lenses for two wavelengths from the visible spectrum: 532 and 633 nm, in order to determine whether there are any discernible wavelength ...

Researchers at Beijing University of Chemical Technology (BUCT) and BOE Technology Group Co., Ltd. (BOE) have developed a novel type of transparent organic–inorganic hybrid photoresist with highly ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...
