When an electric field is applied across the crystal, it changes the passing light so it will not pass through a polarization filter.

To use ambient light, the liquid crystal itself is sandwiched between a polarization filter and a reflective surface.

These separately polarized channels are viewed wearing eyeglasses with matching polarization filters.

His mouth felt like sand had been scraped across his tongue and his eyes ached as though he'd been staring at an A6-class star without polarization filters.

They used a light polarization filter to view the crystals.

Light from lamps is normally emitted as a random collection of polarizations, while a polarization filter only passes a fraction of the light.

This is especially useful when working with a polarization filter or close to the subject.

These materials can thus be used as polarization filters.

Within the detector, the light beam gets divided into two and then passed through polarization filters and detected.

He invented the first polarization filter in 1812.
