A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

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 ...

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 ...

WEST LAFAYETTE, Ind. – Engineers at Purdue University are the first researchers to create a material that has a "negative index of refraction" in the wavelength of light used for telecommunications, a ...

A groundbreaking sulfur-rich polymer lens for thermal imaging optics shows high refractive index and LWIR transparency, ...

Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin and ...

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has advanced the characterization and retrieval capability evaluation of microphysical properties of ...

Master Bond UV15-7LRI produces durable, tough and chemically resistant bonds, seals or coatings with excellent optical and electrical insulation properties. It has a low 1.481 refractive index and a ...
