Scientists have demonstrated how to manipulate light by using time-varying media in the form of specialized nanomaterials.

Light changes speed as it passes from one medium to another. This is called refraction. The frequency of light does not change as it refracts. The refractive index of a material is a measure of ...

It is refraction that makes some objects appear to bend when they are viewed through water, like the straw shown here. If the light hits the surface of a glass block at an angle, this change in ...

Technology startup Refraction has received $250,000 in funding from Launch NY as part of its ongoing pre-seed round. The funding will help Refraction scale into the used car dealership market this ...

When suitably cut and mounted between glass cover-slips, naphthalene crystals exhibit the phenomena of conical refraction in a very striking way, and enable their features to be critically examined.

In addition to the objective refraction, the keratometer values and the pachymetry can be determined with precision in a matter of seconds with the PARK 1 ®. The integrated patient data ...
