3. Convergence Angle Test
The convergence angle of the loupe optics is preset according to the working distance.
3.0 To test the convergence angle, draw a single dot on a piece of paper.
Focus on the dot with the loupe optics at the proper working distance. The convergence
settings should not require adjustment unless two dots are seen.
3.1 Two horizontal dots indicate horizontal misalignment. Proceed to Step 4 to correct the
convergence angle.
3.2 In the rare case that two vertical dots indicate a vertical misalignment, the loupes
should be returned to Integra for adjustment.

4. Adjusting Convergence Angle (If Needed)
Before adjusting the convergence angle, set the IPD (see Step 2). Then, follow the
instructions in Step 3.0. There is a convergence error if two horizontal dots are seen. Rotate
the lens barrels to eliminate the horizontal convergence error.
4.0 To adjust the horizontal convergence angle, first look downward at the loupe optics from
the top to see if the barrels are equally angled.
4.1 Barrels out of alignment will appear asymmetrical.
4.2 If a barrel seems out of alignment, loosen both convergence adjustment screws with a
Phillips screwdriver.
4.3 Adjust one or both barrels so they are pointing slightly and equally inward.
4.4 Slightly tighten both screws to keep them in alignment. Focus on the dot from Step 3. If
two dots are still seen, repeat Steps 4.0 through 4.4 until one dot is seen and both barrels are
pointing inward equally. Once set, tighten both convergence screws on each barrel.
