A ready-made solution for terahertz imaging:
TPX and PTFE lenses and optical systems operating in the THz range.
Plastic plano-raised lenses are made of Polytetrafluoroethylene (Virgin White PTFE, Teflon®), which has a low dielectric constant of approximately 1.96 @ 520 GHz with an index of refraction of 1.4. The THz range can be communicated as the recurrence scope of 300 GHz to 10 THz or the wavelength scope of 30 μm to 1 mm.
