High contrast Broadband Millimeter-Wave and Far-Infrared Polarizer P01

Highcontrast grid array polarizer for the far-infrared and millimeter-wave region. A polarization contrast better than Tp/Ts = 10,000 : 1 is reached.

  • Very high degree of polarization P = (Tp - Ts)/(Tp + Ts) > 99.99%
  • Thin, compact, rotable
  • Continuous millimeter-wave to far-ir-coverage
  • No substrate - there is no beam deviation and no substrate dependent dispersion
  • Wide wavelength range > 2.5mm to 12µm (equivalent to 4 ....... 800cm-1 or 120GHz ....... 24THz)
  • Standard clear apertures: 25 and 40mm diameter
  • Application: THz-, fir-, mir-spectroscopy, polarimetry, ellipsometry

The polarizer is mounted in a 34.8mm dia. x 8mm thick metal ring.
