Moxtek Polarisers

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.

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

Moxtek can provide protective mounting for their polariser plates that reduce the risk of damaging the wire-grid polariser structure. These mounts come in standard sizes shown in the included datasheet.

Pixelated Polarisers using micro-pattern grids

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 the 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. We offer patterned polarisers for two, three and four-state imaging devices

FEATURES

Low cross-talk
Accurate registration
Allow for single camera systems

UltraViolet Polarisers for UV and broadband applications

Moxtek Ultraviolet polarisers are used for a wide range of UV and broadband applications where performance, contrast, and durability is important. The UVT and UVD Series polarisers offer excellent broadband performance into the IR wavelengths. New applications are emerging.

The UVT and UVD Series ProFlux Nanowire Ultraviolet polarisers offer excellent solutions for UV and DUV applications. High transmission and high contrast choices are available. The high transmission products are indicated by UVT and the high contrast products are indicated by UVD. The UVT series are naturally capable of broadband applications into the NIR spectral range to 4μm.

Use of polarisers in the ultraviolet spectrum is a demanding environment. ProFlux is ready for the challenge.

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.

Heat tolerant visible polarisers

Moxtek visible polarisers are heat tolerant, accept wide angles of incidence, and have high transmission and contrast. These features make them excellent for use in projection applications. Their light weight and small size also make them ideal for use in head mounted displays.

We offer both reflective and absorptive polarisers.

Optimised to provide uniform polarisation

The Moxtek ProFlux^® Ultra Broadband polarisers are optimised to provide uniform polarisation over a broad range from 300 nm to more than 4 microns. The versatility of our high contrast broadband products eliminate the need to switch or rotate multiple polarisers.

Transmission is relatively constant from 400nm to 3.2 microns while contrast increases throughout this range.
