The Insulator Seal division of MDC Vacuum Products, LLC has recently teamed up with a global technology company to develop polarization preserving optical viewports.
Experimental vacuum methods based on the state of polarization and correlated with changes to physical and chemical states require that the light entering or exiting an apparatus preserve the state of polarization.
Stress induced birefringence in viewpoints rotate circularly polarized light and should be avoided in such applications as magneto-optical-Kerr-effect (MOKE) experiments, Bose-Einstein Condensate apparatus (BEC) and in the monitoring of molecular beam epitaxy (MBE) by ellipsometry methods.
