Movement Control Bar - THORLABS Vytran GPX3400 User Manual

GPX3400 and GPX3600 Glass Processors

5.2.10. Movement Control Bar

The seven boxes in the Movement Control Bar permit the user to move the fiber handlers and splice head at will,
by clicking on the forward and back arrows. The radio buttons labeled "Fine", "Medium" and "Coarse" allow the
user to decide how much motion should occur with every click of an arrow. The units indicating the positions are
given in motor steps. The "Home" buttons will move the motors to their home positions. If the "Sync ..." check box
is checked when moving a motor, than the corresponding motor on the other block will move an equal distance to
maintain the relative distance and orientation between the two holding blocks.

The "Left Block" box enables the user to move the left fiber handler in and out.
The number shown is the position of the left block in microns, and the positive
direction is defined as "in" or towards the splice head. Thus, for the left block,
positive motion is to the right, with "0" being the outmost position.
The "Left Pivot" box enables the user to pivot the left fiber holding block for
alignment in the back view.
The "Left Rotation" box enables the user to rotate the left barrel for the sake of
aligning stress members in PM fiber, aligning cores in eccentric-core fiber, or
aligning surface features in non-circular fiber.
The "Splice Head" box enables the user to move the splice head left or right.
Positive motion is to the right.
