50 mm focal length lens.
Lytid’s high-quality PTFE lenses provide excellent performances across the sub-THz and THz band. The low absorption coefficient of PTFE optics (<0.8 cm-1 up to 1 THz) in combination with low insertion loss (refractive index of ~1.4) make it a prime solution for a variety of THz and sub-mm systems within a wide frequency range, from 75 GHz up to 2 THz.
The PTFE lenses incorporate standard geometries with diameters between 1″ to 6″, focal lengths from 500 mm down to 40 mm through plano-convex, plano-aspheric or double-aspheric profiles.
> Highly-suitable material for THz applications
> Wide range of focal lengths and dimensions
> Minimal insertion losses
> Cost-effective optic
