Deflector shield/Legends

A shield (also known as a deflector shield) is a invisible force of energy that is generated by shield generators. These generators are placed on planets, droids, starships and individual buildings. The primary purpose of the shield is to block or deflect projectiles and lasers from hitting the object being protected.

The use of shields is changed as time passes but they are see in the first scene of Episode I: The Phantom Menace.

The shields use blocked lasers but droids could pass through because their armor is much greater. Some of the Trade Federation droids are equipped with shields making them invincible in infantry combat. A human cannot carry a shield because it is extremely radioactive.

Shields used in starships can handle massive amounts of energy or punishment. However it is possible to destroy a shield buy attacking one spot with lots of energy at one time. This is demonstrated in Return of the Jedi when Admiral Ackbar orders a concentrated bombardment of Executor, which disables its shields. Once the shields are down, the starship can be attacked. However, by diverting other energy to the shields, it can be regenerated.

Note: Some shield generators rate "ray-shield" and "particle-shield". Ray-shield can only block lasers or energy while the particle shield will stop physical projectiles.
