Ø25.4mm Polarization Rotators

 Ø25.4mm Polarization Rotators

Product name : Ø25.4mm Polarization Rotators
Description :
Polarization Rotators rotate polarization at a fixed angle and represent a good alternative to retardation waveplates for narrow-waveband lasers.

The rotation of polarization is caused by a property called optical activity, which is natural to quartz crystal and other enantiomorphous materials. There are “right-handed” and “left-handed” quartz that rotates the polarization clockwise or counterclockwise, respectively. As the rotators are c-cut, the rotation of polarization occurs independently of the component’s rotation around the optical axis, thus component is alignment-insensitive and the only requirement is that the incident beam must be perpendicular to rotator’s aperture.

Altechna offers rotators with fixed polarization rotation angles of 45° or 90°, including antireflection coatings for the designed wavelength. For more convenient use, all rotators are mounted in black anodized aluminum mounts.
