Product Family Description

  • High Contrast, Reflective Design
  • Excellent Visible and NIR Performance
  • Superior Durability Under High Temperatures and Humidity

TECHSPEC® Wire Grid Polarizing Film is ideal for applications requiring high contrast polarization, including pico projectors, polarizing beamsplitters, and heads up displays. Wire Grid Polarizing Film is designed to transmit the required polarization state while reflecting the unwanted state. Since these polarizers have spectrally flat performance at angle of incidences up to 45°, they can also be used as polarizing beamsplitters. Additionally, TECHSPEC® Wire Grid Polarizing Film feature excellent durability in high temperature or humid environments and provide excellent performance in the visible and NIR spectra from 400 – 1200nm.

Note: Due to the wire grid being exposed, special care should be taken when handling to prevent damage to the polarizer.
