Polarization Optics Selection Guide

Selecting the proper polarization optic for your application requires making a number of choices. A few of the many considerations include: polarization function, extinction ratio, transmission efficiency, laser damage resistance, wavefront distortion, and certainly cost. Newport also offers a wide variety of Rotational Mounts for mounting polarization optics. The information in this section should help in comparing the available choices from Newport.
