Loss Estimation
: This button estimates the loss in a splice based on the appearance of the
cores in the splice region. For more accurate estimation, you need to have the correct calibration
file. Please contact Thorlabs for more assistance
.
One Button Process:
This executes the Splice Routine found under Splice, Splice Process
Editor, which generally includes alignment and gapping. The blue button labeled “START” on the
front right corner of the LFS4100 has the same function.
Stop
: This button stops whatever process is being executed. The blue button labeled “STOP” on
the front right corner of the LFS4100 has the same function.
Reset
: This button resets the parameters of the LFS4100 to the default values
.
Initialize
: This button initializes the unit. The system should automatically initialize after the
power is on. If the machine is stopped due to any reason, it should be reinitialized by clicking on
this button.
5.8. Camera Image
The camera image shown below is a side view (“Front” or “Back”) of a pair of fibers. Front and back views are
captured with the help of mirrors on the mirror tower, and feature back-lighting from LEDs in the ring illuminator.
Another way to get an edge view is to view the fiber pair straight on. This is accomplished by clicking on Center
View in the Macro Toolbar. In this case the fiber will be backlit by an LED in the mirror tower. Finally, the unit is
also capable of viewing fibers end-on in “Left” or “Right” view. This is also accomplished with mirrors on the mirror
tower, but in this case the illumination comes from light injected into the fibers in the fiber holding block lids.
Figure 16 Fiber Image from Camera Tower
The camera image is fitted to the image window, which means that it may be squished or stretched horizontally
and vertically. This becomes apparent when the circular end of a fiber is imaged and appears as an oval. To
remedy this, right-click in the image window and activate the Horizontal Scrollbar and Vertical Scrollbar. Doing so
will force every pixel from the camera to be treated as one pixel on the screen.
Right clicking in the image window also enables the user to turn the cross-hairs and alignment guides on or off
and to save an image as a bitmap or a TIF.
