advertisement:

This design is suitable for commercial, military, and space applications requiring a helium-leaktight vacuum pressure window.

The NASA Deep Space Network (DSN) uses commercial waveguide windows on the output waveguide of Ka-band (32 GHz) low-noise amplifiers. Mechanical failure of these windows resulted in an unacceptable loss in tracking time.
