Terahertz Lens Terahertz Wave Lens THzLenses PTFE Lens Product Description:

Terahertz lenses Terahertz wave lenses Terahertz lenses PTFE lenses are part of the solution for terahertz imaging, and Terasense provides PTFE lenses to operate optical systems in the terahertz range. The plastic plano convex lens is made of polytetrafluoroethylene (PTFE) (Virgin White PTFE) ®) Made with a low dielectric constant of approximately 1.96 @ 520 GHz and a refractive index of 1.4. It can transmit terahertz waves ranging from 300 GHz to 10 THz or wavelengths from 30 μ m to 1mm. The low dielectric constant of PTFE ensures relatively low insertion loss. The typical working range of PTFE is up to approximately 2 THz.

The terahertz (THz) range refers to the frequency range from 300 GHz to 10 THz, or the wavelength range from 30 μ m to 1 mm. Until recently, the THz range has been a relatively rare band in the electromagnetic spectrum; But in recent years, terahertz has received widespread attention and has been applied in various fields such as spectroscopy, astronomy, remote sensing, and security (terahertz imaging). In the electromagnetic spectrum, the terahertz band falls between the microwave and optical bands. This position affects the integration of microwave and optical technologies in the terahertz field.
