THz Polarizers

polarizaiton rotator

 

Polarization Rotator

The polarization Rotator is a wire grid polarizer combined with a mounted mirror placed at an adjustable distance behind the polarizer. It is designed to take an incoming linearly polarized signal and adjust the polarization elliptically.

Free Standing Wire Grid Polarizers

Microtech offers three types of polarizers for THz:

These polarizers are made of 10 µm, 15 µm or 20 µm tungsten wire wound on a circular frame with spacing ranging from 25 µm to 200 µm.

Wire Grid Polarizer Holders

We carry three types of rotating holders for the wire grid polarizers. 

Model RH1 is designed for 4” diameter polarizers, and enables a 360° rotation. 

Model RH2 is designed for 4” diameter polarizers, and enables 2-axis adjustments and 360° rotation.

Model RH3 is designed for 50 mm diameter polarizers (S-model polarizers). Enables 360° rotation.
