RSC-51E

A polarization rotator or a waveplate rotator is a mechanical device that rotates a polarizer filter or an optical wave plate.

The optical polarizer acts like a filter that allows transmittance of linearly polarized light only along its polarization axis and reduces the intensity of transmitted light according to

.

The optical waveplate shifts the polarization of linearly polarized light with little or no loss of intensity.

Motorized polarization rotators or wave plate rotators are commonly used in applications involving optics and lasers.

The RSC-51E motorized rotator allows very precise, continuous and smooth adjustment of the rotation angle from a computer or another electronic programmable machine.
