Viewport

A viewport, also known as a window or porthole, was a framework that contained a pane of transparent material and was built into a wall to admit light. Starships and space stations were commonly equipped with viewports, as were ground-based structures. A viewport embedded in a rooftop was referred to as a skylight.

The main component of both viewscreens and portholes aboard starships was the alloy transparisteel, which were made of the mineral lommite, the primary export of the planet Eriadu. Glass was also used.
