Photoreceptor

Canon Legends version → Linked from 353 articles

Photoreceptors, also known as visual sensors, was a technical name for the optical sensors of a droid. They were the equivalent to an eye. Numbers of photoreceptors could vary depending on the size and model of a droid. For instance, R2-D2 had one, while EV-9D9 had three. Many droids, like C-3PO, had two. Some could have them in different areas. For instance, General Grievous' MagnaGuards had a built-in photoreceptor in their torso to allow them to fight without their heads.
