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 ...

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 ...
