Overview: Crystalline Quartz Polarization Rotators rotate the polarization plane of an incident beam by a fixed
angle, regardless of the rotator’s alignment relative to the beam’s
polarization. Polarization rotators are a good alternative to
waveplates with regards to rotating polarization by a specific
angle. They produce a rotation in polarization caused by the
optical activity naturally present in quartz crystals being
independent of the rotator’s orientation around the optical axis.
The Crystalline Quartz Polarization Rotators only need to be
aligned perpendicular to the direction of propagation of light. We
offer crystal quartz rotators with fixed 45° or 90° rotation at
typical wavelengths such as 355nm, 532nm, 633nm, 1053nm and 1064nm.
