Cube and Plate Polarizers

Through stringent polishing and coating process parameters, PFG is able to produce thin-film cube or plate polarizers. These 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. Moreover, PFG manufacture optical lenses, beam splitters, and optical prisms.

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.

Plate Polarizers


There are lots of different devices that produce or manipulate polarized light waves. A polarizer simply allows one polarization state to pass through while blocking all other states. All polarizers make use of one of the following four physical phenomena:

  • Reflection – Light rays impinging upon a reflective surface will exhibit polarization. For example, unpolarized sunlight impinging upon a horizontal glass plane will have much of its vertically polarized light absorbed. Thus, the reflected light will be mostly composed of horizontally composed light.
  • Selective absorption – The polarizer is composed of anisotropic material that selectively absorbs one of the perpendicular electric fields while allowing the other to pass through undisturbed.
  • Scattering – As unpolarized light rays travel through space, they pass through molecules. The electrons of these molecules vibrate perpendicular to the direction of the light’s propagation, re-emitting the light in the direction of its vibration. These new rays are linearly polarized along this electron vibration plane.
  • Double refraction – The polarizer is composed of a material that exhibits two indices of refraction. The polarization state and direction of the incoming light affect the refraction, and thus the resulting polarization state after passing through the material.

    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 includes 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.

    Polarizing Filters

    Linear polarizing filters increase color and contrast. The reflected light is a glare that also washes out color in imaging systems. Moreover, a circular polarizer filter can be used on-camera filters with a metering device also found on CPL auto focus SLR’s camera lens. A polarizer filter corrects this problem producing polaroid color saturation, deep polarizing effect, or extensive blue skies. Plastics in non-metallic surfaces become birefringent when under the stress almost like a wave retarder. From substrate preparation to optical coating, and product packaging we apply our state-of-the-art expertise to both stock and custom polarization optics.

    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 of 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.

    Does laser contain unpolarized light waves? Birefringent polarizers work to separate an incident beam in two beams. PFG provides wire grid polarizers, IR & dichroic polarizers, neutral density filter, circular polarizer films, and more.

    Circular vs linear polarizer

    The main difference in X-ray absorption between two types of the plane of incidence polarization is called dichroism. Polarization state changes in absorption meaning the difference in the color of substances in the visible circularly polarized light through linear polarizer intensity region. The direction contains the degree of polarization modules that relies on the angle of incidence and the refraction index of the surface. We offer a wide range of waveplates, as well as some polarization rotators and other new products.
