Nanowire Grid Polarizers

Nanowire Grid Polarizers

PIKE Technologies introduces an innovative new line of high-contrast polarizers covering the UV region and the Vis to NIR region. Using nanofabricating techniques, wire grid lines at a 100-nm pitch are etched on fused silica or glass substrate resulting in a high-performance polarizer. Compared to a traditional calcite polarizer, the large acceptance angle of the nanowire grid polarizer, greater than 20 degrees, eases alignment concerns during use. Additionally, the compact size makes these polarizers ideal for use in confined spaces. The element diameter is 25 mm and has a clear aperture of 19 mm. The polarizer fits a 2 x 3 inch slide mount. 

  • Thin profile
  • Large acceptance angle, up to 20 degrees
  • High transmission and high contrast choices
  • Manual and automated versions
