Terahertz Low Pass Filters, THz

Manufacturer's part number :



Microtech Instruments

Description :

THz low pass filter is constructed from a microstructured material that blocks the visible through mid IR while passing THz beams. It is an excellent filter for optical THz generation systems such as time domain THz spectroscopy systems. It has optimal characteristics for use in zinc telluride based systems and for typical photo conductive switch systems as well.

  • Quote and availability


  • Transmission range (700 to 850 nm) : <0.01%
  • At wavelengths longer than 975 nm the transmission is <0.1%
  • Mechanical holder diameter: 2" diameter
  • Clear aperture: 43 mm
  • Benefits

  • Transmission of THz waves is above 80% across the .1 to 3 THz range making this an excellent filter even for broadband THz applications.
  • THz measurements were done up to 1 THz with our compact THz spectrometer (TScan-1000) and with additional optical THz generation for the above 1 THz range.
