§ 4.12.
Adjustment of Focus-Mechanical-Stopper’s Position
1.
Prepare 250µm fiber with 30mm strip section and load into both V-groove s.
2.
Using Focus Motor, manually adjust focal point to produce sharp fiber core image.
3.
Refer to Fig. 4.13.1.
4.
Measure gap “g” from Focus-Arm-A to Focus-Arm-B. Note – Measure with Block Gauges.
5.
Calculate Block Gauge thickness.
Formula - (Block Gauge thickness = ”g”-1mm).
6.
Loosen the set-screw (M4×6) for Focus-Arm-Stopper.
7.
Place Block Gauge between Focus-Arm-A and Focus-Arm-B, apply pressure by pressing Focus-
Arm-B against Focus-Arm-A.
8.
Apply pressure by pushing Focus-Mechanical-Stopper up. Attach set-screw (M4×6, T=10, W point
type, SLG) to Focus- mechanical-Stopper.
Fix the state of pressing
Focus-Stopper
against
Focus-Arm-A
.

Measure the gap "g" from
Focus-Arm-A
to
Focus-Arm-B
.
Insert "t" milimaters thick gauge between
Focus-Arm-A
and
Focus-Arm-B
.
And press
Focus-Arm-B
against this gauge.

Note - New XY-block has the rubber bushing to resist shock created by stopper pin impact. In this case,
change the block gauge thickness (g-0.8) mm.
