Infrared (IR) Wire Grid Polarizers

Infrared (IR) Wire Grid Polarizers
  • Designed for Wavelengths Ranging from 2 - 30μm
  • Holographic Polarizers Available in Many Substrates
  • Ruled Polarizers Ideal for High-Power Lasers
  • 360° Rotation Using Metric Polarizer Mounts

Infrared (IR) Wire Grid Polarizers are used to polarize light from unpolarized infrared laser sources, as well as attenuate light from polarized ones. When two wire grid polarizers are used together, high extinction ratios greater than 40,000:1 can be achieved. The polarization axis of each polarizer is marked by two white lines etched into the surface of its protective ring. We offer both ruled and holographic configurations. Note: Special care should be taken when handling KRS-5 and Zinc Selenide as they are toxic materials. Always wear rubber or plastic gloves to avoid risk of contamination.

Holographic Wire Grid Polarizers

Holographic wire grid polarizers are manufactured by a special holographic technique that creates sub-micron wire grid spacing. Compared to conventional ruled wire grid methods, the holographic method creates finer groove spacing which optimizes short wavelength performance. We offer holographic wire grid polarizers of Barium Fluoride (BaF2), Zinc Selenide (ZnSe), Thalium Bromoiodiode (KRS-5), and Germanium (Ge).

Ruled Wire Grid Polarizers

Ruled wire grid polarizers are available on Calcium Fluoride (CaF2) and Zinc Selenide (ZnSe). Ruled holographic gratings feature precisely spaced grooves formed directly on the surface of the substrate. The ruling process forms sharp, well defined peaks which are then coated with aluminum by vacuum deposition at an oblique angle. The direct ruling and coating process results in a series of closely spaced, highly conductive wires with a high extinction ratio and an inherently high damage threshold.
