Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

A paradox that puzzled a generation of solar and atomic physicists – and occasionally pitted theories from one field against the other – has been resolved. The paradox concerns the polarization of ...

McPherson (Chelmsford MA USA) is pleased to announce a new vacuum ultraviolet spectral test system VUV-STS. The new system measures reflectance as a function of angle of incidence. It measures optical ...

A new device for rotating the polarization of terahertz radiation has been created by accident by researchers in the US. While practical applications remain unclear, the discovery could boost the ...

The coatings have been designed to hold both the s- and p-polarization components to the same ratio of reflection-to-transmission over a specific laser wavelength region. This means that they will not ...
