12.7 mm Post Holder Mount MBB-BA2

JCOPTIX post-holder mounting bases commonly secure Ø12.7 mm standard posts to optical tables or breadboards. Countersunk holes at the bottom allow M6 screws with washers to secure a base anywhere along the elongated slot, translate it along the slot for coarse positioning, or rotate it about the screw for coarse angular adjustment. Bases can also directly mount Ø12.7 mm posts. The source lists six standard types: single straight slot, double straight slots, double U-slots, cross-shaped elongated slots, double arc slots, and rotating single straight slot. MBB-05S has an M6×25 straight U-slot for translation or angular adjustment about the screw. MBB-05D has two collinear M6×20 straight U-slots for coarse translation. MBB-05L has two parallel U-slots for coarse translation and three M6 countersunk holes spaced 12.5 mm apart, allowing 2 post holders to be mounted for compact optical systems. MBB-05C has two perpendicular M6 countersunk slots in the center, 8 M4 and 8 M6 threaded holes on top for multidirectional component mounting, M4 countersunk holes on the back, and M4 threaded side holes for joining two plates perpendicularly. MBB-05A has 3 central M6 countersunk holes spaced 12.5 mm apart; its arc slots permit ±40° rotation about the center. MBA-UPH has a fork clamp rotating through 360°, accepts standard post holders and 25 mm baseless posts, and permits selection among multiple breadboard holes. Its magnetic underside attaches to an optical table for preliminary positioning. MBB-05E has straight slots on four sides. On top are 8 M6 threaded holes spaced 50 mm and 60 mm apart, 4 M4 threaded holes spaced 40 mm apart, 4 M3 countersunk holes spaced 32 mm apart, 4 M2 countersunk holes spaced 20 mm apart, 4 opposing M6 elongated slots spaced 50 mm apart, and an M6 countersunk mounting hole. It can adapt various translation stages.
