Cube and Plate Polarizers

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.

Tight centering, truncation, high included angle or long radii – we use best practices developed from decades-long experience to achieve timely and efficient production. We have a vast library of test plates and many current model Zygo interferometers, all with complete reference spheres for accurate surface measurement.

A polarization optic is capable of selecting or changing specific polarizations. We can provide a diverse portfolio of polarizing cube beamsplitters, waveplates, and linear polarizers which operate over IR, UV, and visible spectral ranges. Quarter-wave and half-wave plate polarizer can come in achromatic, multiple-order, or zero-order versions. Our variety of linear polarizers include Polaror dichroic glass, laminated sheets, Calcite crystal types, and laminated polymer films. Thin film polarizers can be utilized in high energy Nd:YAG applications as well as Ultrafast lasers and Ultrashort pulse uses.

Polarization of Light

The polarization of light, both manipulating it and understanding it, is absolutely critical for optical uses. Often we see optical designs ignoring its polarization, instead paying attention only to the intensity and wavelength. Polarization is an essential aspect that can have an effect on optical systems that are not even specifically measuring it. It can affect many things, such as preventing unwanted back reflections, altering filter cut-off wavelengths, and even changing the focus of laser beams. Metrology applications benefit from light polarization as well, through pharmaceutical ingredient analysis, biological microscopy, and stress analysis of materials like glass or plastic. Materials can absorb varying degrees of different polarizations, which is a critical aspect of 3D movies, glare-reduction eyewear, and LCD screens.
