Photoreceptor/Legends

""Agonized Exclamation: Ah, my photoreceptors! My photoreceptors!""

- An HK-50 series assassin droid, tortured by HK-47

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.

Design
The photoreceptors of droids were often made to resemble the eyes of species with which the droids would interact. The LOM-series protocol droid's photoreceptors were made to look familiar to insectoid species such as the Brizzits, Verpines, Gand, Yam'rii and Xi'Dec, while the CZ-series communications/business droid had optical sensors resembling the eyes of the Stacchati.
