1. How to align lightlever optics
Mirror bracket
Clamp screw
Access
hole
LightLever Pickoff tube mounted above prism box

2. Pickoff tube pieces pickoff tube lens lens slider wrench
mirror bracket

3. To inspect optics, first loosen clamp screw
with 3/32” hex key

4. Remove pickoff tube
Be careful not to touch pellicle against edge of hole

5. Inspect pellicle Film should be flat and smooth
Remove dirt with puff of air
Do not touch film with fingers or brush

6. Remove mirror bracket
with 0.035” hex key (0.9 mm)

7. Use wrench to remove slider
Twist and pull

8. Inspect lens for dirt

9. Reassemble pickoff tube
Be careful tube is not twisted in mount

10. Place pickoff back into hole
Be careful not to touch pellicle against edge of hole

11. Align mirror bracket straight up/down and tighten clamp screw

12. Remove mirror bracket

13. so bare tube is sticking out

14. Turn on trap laser and adjust control rods so that trap focus is in middle of TV screen

15. Place IR indicator card 9” away from end of tube
Wear laser goggles to protect your eyes

16. Beam should focus to a point 9”distant and 5” above the table
Fake spot shown
Real spot not so bright

17. Move lens slider in/out with wrench to adjust 9” focal distance

18. Loosen clamp screw and pull pickoff tube in/out to adjust 5” focal height
but do not rotate tube which changes twist of pellicle

19. Beam spot moves Up/Down when pickoff tube slides In/Out
Make spot 5”
above table
slide tube in/out

20. Tighten clamp screw and replace mirror bracket

21. Place IR detector card inside instrument head
Spot should be visible near position detector
Fake spot shown here
Real spot not so bright

22. If spot is not visible try twisting position of mirror bracket until you see spot on card

23. Adjust LightLever mirror screws with 5/64” (2mm) hex wrench

24. so as to put beam inside PSD target

25. Move beam up/down and right/left using control rods

26. Problem : Strange triangle pattern in LL window
Problem : Strange triangle pattern in LL window. Solution: Be sure spot passes through middle of TV screen and adjust light-lever mirror screws to center spot on PSD target

27. Now spot is centered on detector so pattern moves up/down and right/left with control rods

28. If pattern is tilted more than 10 degrees try twisting pellicle relative to mirror

29. The End
