3 Optical Alignment
Warning: Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
Warning: The SuperK CONNECT together with a SuperK laser system constitutes
a class 4 laser source and must be regarded as a potential hazard to the operator.
Make sure to wear laser protective eyewear when operating the SuperK CON-
NECT and when aligning its optical output.
Aligning the FDS
Overall process
Before using a newly installed FDS system, it requires alignment. When the FDS
is aligned, emission coupling efficiency from the free-space output beam to the
fiber is maximized. The FDS includes an alignment tool which is inserted into the
output port of the CONNECT during coarse alignment. Follow the procedures
below to align and couple the beam with the fiber of the FDS:
1. Procedure 3 “Pre-alignment”
2. Procedure 4 “Coarse alignment”
3. Procedure 5 “Fine Alignment of the assembled Fiber Delivery System”
Note: For laser operating instructions, refer to your SuperK laser’s Product Guide .

Pre-alignment
Caution: Before shipping, all SuperK CONNECTs are both pre-aligned and coarse
aligned at the factory. ONLY perform the following pre-alignment procedure if the
alignment has been drastically altered.
Procedure 3 Pre-alignment
Before using the alignment tool, roughly center the output beam from the
CONNECT using the following pre-alignment steps:
1. Remove the FD from the CONNECT so that its output port is empty.
