THz Lenses

 Lytid provides a wide range of high-quality PTFE (Polytetrafluoroethylene) lenses, a plastic which displays good compatibilities and excellent performances throughout the THz range (75 GHz up to 2 THz band).

This solid material has a density of about 2.2g/cm3 and can be use easily. The low absorption coefficient of PTFE optics in combination with low insertion loss (refractive index of ~1.43) within wide wavelength region of THz make it a great option for divers uses in THz domain.

These lenses are largely employed in applications such as astronomy, non-destructive testing, quality control, thickness measurement,…

Apart from standard size of lenses, we could also provide custom optic components with a high precision to satisfy specific needs for certain activities. The geometry could be Plano-convex, Plano-aspheric or Double-aspheric, with a diameter beteween 1″ to 6″. Don’t hesitate to ask us for any custom request or question about our products.

Lytid provide also different lenses as HRFZ-SI with anti reflexion coating, Zeonex, TPX …, with a wide selection of geometry (Aspherical, Plano-convex, plano-convex with central hole, bi-convex, sphere, hypo-hemisphere, bullet-lens, negative meniscus, cylindrical hyper-hemisphere, cylindrical plano-convex …)
