Ultra-High Contrast Linear Polarizer

Our UHPUV series polarizers offer high contrast in the UV from 360 to 400 nm and our UHP-LNIR series polarizers offer high contrast over the exceptionally broad range from 650 to 5000 nm.

  • Extremely high contrast, greater than 10,000,000:1
  • Unlaminated part usable to 400° C
  • Wavelength ranges within 340 to 5000 nm
  • Absorptive dichroic glass
