Assembly Instructions
1. Attach part 1 to the spectrograph wall (dashed line in illustration) with the socket
head screws provided.
2. Leaving 1/4" of thread exposed, mount the three (3) hex head screws to part 3.
3. Mount the adapter to the detector flange and rotate the adapter so the screw heads are
over the narrow end of the slots.
4. Tighten the screws.
5. Gently insert part 3 into part 1 and fasten with the setscrew.
Note: Adapter parts are machined to provide a tight fit. It is necessary to rotate the detector
back and forth when inserting into the spectrograph adapter. Do not force the two parts of the
adapter together, as they can be permanently damaged by excessive force.
