- "Hold it right there! I won't let you through! I-I saw what you did to the others, Jedi scum! But you won't do it to me ‐ even your s-sorcery can't get through 15 centimeters of Imperial-manufactured transparisteel! Right?"

Transparisteel was a hardy and transparent material that was primarily used to make windows[2] and other parts of starfighters, such as cockpit canopies.[3] A major component of transparisteel was lommite ore.[2] Transparisteel windows could be created in a way that made them blaster-proof,[4] as is with the Galactic Empire's TIE/ln space superiority starfighter,[5] but not lightsaber-proof.[6]
The eye sockets of Darth Vader's helmet were made of transparisteel.[7]
