Polarizers – Polarizer Coatings

Through stringent polishing and coating process parameters, PFG is able to produce thin film cube or plate polarizers that deliver an impressive combination of high extinction ratio, high damage threshold, low loss, excellent mechanical durability and long operational lifetime. We produce a variety of polarizers in the ultraviolet, visible and mid-wave IR wavelengths with many split ratios.

Human eyes have no ability to perceive the polarization of light. Also, the most of the optical detectors do not carry sensitivity of the polarization. For this reason, filters that selectively transmit the light with specific polarization or optics that can change the polarization state become necessary. Custom designs need not be more expensive than standard coatings. In many cases a simple modification to a standard coating design can greatly enhance performance on your specific application at little or no additional cost. Sometimes, however, applications require new and innovative coating designs to meet the task.
