Z-90 hardlight shield

The Z-90 Photonic Coalescence Emitter/Aegis, more commonly known as the Hardlight Shield, is a Forerunner anti-personnel shielding system. Like other examples of hard light technology, it works by using a photon emitter to fuse light particles into a dissipative barrier.

Hardlight shields are frequently employed by the ground forces of the mechanical Prometheans, with Watchers providing different types of shield for Knight and Crawlers in combat. This technology can be adapted for use with the MJOLNIR Powered Assault Armor, allowing Spartans to use the shield to protect themselves from incoming fire, although raising the shield renders the user unable to use weapons.

Trivia
The designation "Aegis" is likely a reference to the Aegis, a shield carried by several divine figures in Greek Mythology.
