Polarization Plane and Scatter

When applied to metal optics, there is no perceptible change in performance in either the S or P polarization plane. Laser Gold plating does not increase scatter, in fact, certain customers have actually reported reduced scatter after Laser Gold plating. When Laser Gold is applied over glass, Zerodur and BK7 substrates, differences in the S & P polarization plane have been detected. In other words, processes that involve vapor deposition prior to the Laser Gold application may have an impact.
