Title: IMPROVED PRESSURE WINDOW FOR A MICROWAVE WAVEGUIDE INTERFACE
Abstract:
A pressure window for a microwave waveguide interface is disclosed. The pressure window has a first side arranged to be a pressurized side when the pressure window is installed in the microwave waveguide interface. The pressure window comprises a first mark and a second mark. The first and the second mark are arranged to be detectable from an exterior of the waveguide interface and distinguishable from each other, such that an orientation of the pressurized side of the pressure window relative to an orientation of the waveguide interface is unambiguously detectable based on the first and the second mark in relation to the orientation of the waveguide interface.
