Photoreceptor

Legends Canon version → Linked from 405 articles

Legends. This article is part of Legends: the expanded-universe stories that Lucasfilm set apart from canon in 2014.

Photoreceptors, sometimes known as optical sensors, optic visors, visual sensors, lenses, or simply optics, were the visual "organs" of most droids, also used by many cyborgs.

They were often sensitive to a wider visual spectrum than a typical humanoid eye. Droids could have many photoreceptors on their bodies, sometimes highly specialized.

Some droids seemed unable to see with only one photoreceptor activated; this happened to Anakin Skywalker's protocol droid, C-3PO.

Zam Wesell's ASN-121 assassin droid featured an infrared photoreceptor.
