Abstract

A microwave window for the spatial, pressure-impervious and diffusion-impervious separation and microwave connection of a first space from/to a second space, and a level-measuring system that works according to the radar principle, is provided with a barrier that has two opposite sides and is at least partially permeable to microwaves. To provide a microwave window that makes possible a reliable sealing of a process space and exact measurement, the microwave window has the barrier designed as a disk on at least one side of which at least one plano-convex dielectric lens, which has an essentially homogenous body.
