Polarization Rotators

Polarization rotators offer 45° or 90° rotation at a given wavelength. The optical axis in a polarization rotator is perpendicular to the polished face of the optic. The result is that the orientation of linearly polarized light is rotated as it propagates through the device. This effect is independant of the axial rotation of the device.

As with all of our optics, we will gladly provide these items custom designed to your particular requirements. As an alternative, we offer a selection of standard items as specified below.

Quality Assurance

We take quality control very seriously: we rely on accurate, widely recognized measurement systems for testing our optics. The following table indicates the accuracy of measurement for the most relevant parameters.

Surface figure: λ/20
Angle: 0,5 arcsec
Radius: 0,01%
Focal length: 0,03%-0,3%
Centration: +/-0,2µm or +/-2 arcsec
Wavelength: +/-0,3nm (190-1100nm)
