Terahertz Wave Plate

A16394-04

This is a Fresnel rhomb wave plate for controlling terahertz wave polarization. The adoption of Fresnel rhomb makes it possible to handle a terahertz wave over a broad band. In addition, stacking total reflection prisms simultaneously achieves a large aperture and a small size of the component. The prisms are made of high-resistivity silicon, which highly transmits a terahertz wave.

Features

  • Optical component for polarization control of terahertz wave
