Waveplate 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 • Fresnel rhomb wave plate with co-axial design for input and output terahertz beams • Broadband (typical value: 0.5 THz to 2.5 THz) Application • Terahertz wave phase control • Terahertz polarization imaging • THz-STM (scanning tunneling microscope)
