If Trap 2 is lost from the field of view, follow the steps below to bring it back using the Z-Finder camera in Bluelake. You’ll be looking for the second back reflection to help you re-locate the trap.
Tip: If Trap 2 appears at any point, you can skip the remaining steps and reposition it directly.

‍

1. Open the Z-Finder and Adjust the Objective

2. Check Initial System Settings

3. Move Trap 2 to the Right Limit

• Select Trap 2.
• Use the joystick to move it all the way to the right.
• Stop when the clicking noise stops. This indicates the trap has reached its limit.
  
  ‍

4. Move Trap 2 to the Left Limit with Large Step Size

• In the Trap movement box (red box), enter a large step size, such as 10,000 nm (10 µm).
• While counting the clicks, click the left arrow to move Trap 2 all the way to the left limit.
• Stop when the clicking noise ceases (you’ve reached the end). This will require many clicks.
  ‍

5. Center Trap 2 in X

• Divide the total number of clicks it took to go from right to left by 2.
• Move that many steps back to the right, to position Trap 2 roughly at the center of its X-range.
• Lock the X-direction.

You might already see the second back reflection at this point. If so, skip ahead to adjust the objective and center visually.

‍

6. Move Trap 2 to the Upper Y Limit

• Use the joystick to move Trap 2 upward until the clicking stops.
  
  ‍

7. Move Trap 2 to the Lower Y Limit

• Use the large step size from earlier.
• While counting clicks, click the down arrow until Trap 2 reaches the bottom (no more clicking).
  ‍

8. Center Trap 2 in Y

• Divide the number of clicks by 2.
• Move that many steps back up, centering Trap 2 in the Y-direction.
  
  ‍

9. Final Adjustments in the Z-Finder

• Trap 2 should now be close to its central position and visible in the Z-Finder.
• If the rings are not visible:
  • Slightly raise the objective to widen the back reflections.
  • Move Trap 2 around gently until you locate the reflection.
