Holographic Wire Grid Polarizers with Size (mm) 29 mm dia.

We manufacture holographic wire grid polarizers on ZnSe, CaF2, BaF2, KRS-5 and Ge, covering a wavelength region from 2.5 to 30 microns.

Features

  • 2.5 to 30 microns
  • CaF2, ZnSe, BaF2, Ge and KRS-5 (Thallium Bromide) substrates
  • Finer grid pattern for better low wavelength performance
  • High Transmission
  • High extinction ratios
  • 360° bench mountable, rotary stage for FTIR spectrometers

Anti-reflective Coatings

  • Zinc Selenide’s transmission can be enhanced over a selected wavelength range, typically 9 to 11 microns, by an anti-reflective (AR) coating on the rear surface.
  • Calcium Fluoride and Barium Fluoride have low refractive index values and do not see significant benefit from AR coatings.
  • KRS-5 is not normally AR coated, because this would limit its broad transmission range, which is its primary advantage.
  • Germanium polarizers are AR/AR coated to maximize transmission @10.6μ.
  • Due to the manufacturing process ruled wire grid polarizers are not offered with AR coatings.
