Qty P/N Description
1. 3 2826-0120 Screw, 10-32 1/2, Hex Head, Stainless Steel
Assembly Instructions
1. Make sure that the shipping cover has been removed from the detector port on the
spectrograph.
2. If the spacer plate has been removed, reinstall it on the sliding tube.
3. Leaving 1/4" of thread exposed, mount the three (3) hex head screws to the sliding
tube.
4. Mount the detector flange on the sliding tube assembly and rotate the detector so the
screw heads are over the narrow end of the slots.
5. Tighten the screws.
Note: Adapter parts are machined to provide a tight fit. If you need to remove the sliding
tube from the spectrograph, first loosen the two setscrews that secure it, and then rotate the
tube as you pull it out. If you have removed the sliding tube from the spectrograph, rotate the
sliding tube as you re-insert it, and tighten the setscrews afterwards to secure it. Forcing the
tube into the spectrograph could permanently damage the tube and the spectrograph opening.
