Moxtek linear polarisers

Inorganic wire-grid construction

The Moxtek linear polarisers and beam splitters are constructed completely from inorganic materials. This allows them to be more tolerant to high temperature or high photon flux environments compared to organic polymer film polarisers. This is especially important in UV curing and projection display applications.

All parts are cut from 200 mm diameter wafers, enabling great flexibility in custom shapes or sizes. Cut parts can then be mounted, or encapsulated to add an additional layer of protection.

The wire-grid can be tuned to allow higher transmission or contrast performance. Polarisers are available from the UV right up into the LWIR. The majority of the polarisers are reflective in nature, meaning they transmit the p-polarisation state and reflect the s-polarisation state.

Due to the nature of these components, there exists very few standard configurations. Therefore, please contact us to discuss your specific requirement.

  • Models

    Ultraviolet polarisers

    The ProFlux UV polarisers from Moxtek are available in high transmission (UVT) and high contrast models (UVD). The high contrast model is a doubled part, meaning that it is constructed from two UVT parts placed in series (back-to-back). This has the advantage that only the back (non-wire) side of the part can be handled by the user – therefore offering an inherent level of protection, not possible with the single UVT parts without the addition of a layer of protective cover glass. Additionally the UVD parts are generally mounted (which adds further protection, but increases the thickness of the part and reduces the clear aperture).

    Typical applications include UV curing, forensics, photo-alignment and spectrophotometry. The UVD parts in particular are an excellent alternative to Glan-Taylor or Glan-Thompson components commonly found in commercial spectrophotomer instruments.

    Visible polarisers

    The ProFlux visible polarisers from Moxtek have excellent polarisation uniformity over large apertures, and provide bright, high contrast, and long-lasting performance. These features make them excellent for use in projection applications. Their light weight and small size also make them ideal for use in head up and head mounted displays (HUD/HMD).  The standard visible linear polarisers are reflective and available in high contrast or high transmission configurations.

    Other applications areas include microscopy, spectroscopy, medical research and automotive.

    BIR Series – NIR to SWIR

    The ProFlux BIR series polarisers from Moxtek are designed to operate in the near infrared (NIR) and short wave infrared (SWIR) regions i.e. 700 nm to 2.5 µm. These polarisers are optimised for either high contrast or high transmission.

     

    SIR Series – MWIR to LWIR

    The ProFlux SIR series polarisers from Moxtek are designed to operate in the mid wave (MW) & long wave (LW) infrared regions i.e. 3-5 µm and from 8-12 µm. The SIR polarisers have been designed to have both excellent contrast and transmission.

    Ultra broadband polarisers

    The ProFlux® Ultra Broadband (UBB) polarisers  from Moxtek are optimised to provide uniform polarisation over a broad spectral range. There are two versions available; the UBB02A which is designed to operate from 400 to 1100 nm and the UBB01A which is designed to operate from 300 nm to greater than 4 microns. The versatility of Moxtek high contrast broadband products eliminate the need to switch or rotate multiple polarisers. The transmission of the UBB01A part is very flat across the spectral range, whereas the contrast increases gradually into the longer wavelengths.

    Polarising beam splitter plates

    The ProFlux® polarising beam splitter (PBS) plates from Moxtek are intended for use at an angle of incidence (AOI) of 45°. These parts can are particularly suited to display applications; such as near-to-eye, head up display (HUD) and pico-projectors. Made with highly durable inorganic materials, the PBS plates have high performance and durability providing bright images for the life of a projector.   ProFlux beamsplitters align with the liquid crystal displays to provide uniformity even over large apertures making it an excellent design choice. For ultimate image quality, the parts can be supplied on a thicker flat borofloat substrate which improves the transmitted wavefront error.

    Pixelated polarisers

    Moxtek has created unique Pixelated Polarisers using an array of micro-pattered Nanowire® grids.

    These versatile Pixelated Polarisers can be aligned with cameras, plane arrays, interferometers, and microbolometers without the need for mechanical polariser switches.  Using Moxtek Pixelated Polarisers, vibrant images distinguishing between multiple polarisations across the visible and IR wavelengths can be captured simultaneously in real-time enabling fast, high resolution images.   These polarisers also enable clear 2D and 3D images even in low-light conditions.  Moxtek offer patterned polarisers for two, three and four-state imaging devices.
