prefocus
Factory-set focal point
Prefocus describes a type of lamp base designed so the bulb automatically aligns to the correct position when inserted, requiring no manual adjustment.
Common in automotive and projection applications where precise filament placement matters: prefocus headlight bulbs.
The term also appears as a verb meaning to focus in advance: prefocus the camera before the action starts.
