Thin windows for X‐ray spectrometer flow counters can be produced by stretching unorientated polypropylene film. A piece of the stretched film is clamped into a holder and pressed onto a copper ring made from thin copper sheeting. The mounted window is then suspended in a high vacuum coating unit and flashed with aluminium to a thickness of approximately 20 nm.
