FIGURE 9-61 INTERFACE PILLAR FOR MULTI-HOLDERS
MULTI-HOLDERS
The Multi-Holders fit individually on the Interface pillar using the same
pin location system. Numbers 1 and 2 have a captive centre screw for
fixing to the Interface pillar, where as number 3 has two captive
screws offset from the centre.
FIGURE 9-62 THE MULTI-HOLDERS
16 Position Stub Holder (1)
This can be used for 12.5 mm pin stubs, the Clamp stubs, the
Polished mount holders or any pinned small holder. The pins are held
by spring pressure to prevent vibration or falling out. Using the
location pin position, with homing of the stage, each time will allow
one to map the holder into the stage location system. The 16 Position
Stub Holder fits to the Interface pillar by a captive centre screw.
Angled Stub Holder (2)
This holder can be used for a pre-tilt condition where either there is no
wish to tilt the stage, or additional tilt is needed beyond the stage tilt
capabilities. The set angle is 45° and holds 4× 12.5 mm stubs at this
angle. There are also 2 positions on the top of the holder for 2× 12.5
mm stubs. All stubs are screw fixed. The Angled Stub Holder fits to
the Interface pillar by a captive centre screw.
