Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take ...

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is steered ...

The light trap: The set-up comprises a partially transparent mirror, a thin, weak absorber, two converging lenses and a totally reflecting mirror. Due to precisely calculated interference effects, the ...

If you want to use light efficiently, you have to absorb it as completely as possible. This applies whether the light is being used for photosynthesis – in which green plants transform light into ...

Researchers have uncovered a material perception mechanism with which humans discriminate between reflective and transparent materials (mirror and glass). The research team discovered that the brain ...
