Rotates Polarization by a Fixed Angle Regardless of Incident Polarization Angle
Convenient Replacement of Half-Waveplate for Narrow Waveband Lasers
1064nm, 532nm, and 355nm Anti-Reflection Coatings Available in Both 45° and 90° Rotation Angles
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. Rotators with fixed 45° or 90° rotation at Nd:YAG wavelengths, mounted in a black anodized aluminum mount, are available.
