RT: Polarization Rotators
RT: Polarization Rotators
Alignment-free, high power 90° rotation of linearly polarized light at a single wavelength. Based on the optical activity of crystal quartz, these polarization rotators achieve 90° rotation of linearly polarized light with no more alignment than normal incidence. They are precision polished for a specific wavelength and rotation angle, and are suitable for high power use. Custom wavelengths, sizes, and rotation angles are available upon request.
