  2. Observe the burn mark on the alignment tape.


5.8. Beam Centering Analysis

Correct alignment result:

  • A clean, circular burn mark
  • Precisely centered within the beam expander mount aperture

If the beam is not centered, adjustment is required.


Horizontal (X-Axis) Adjustment

Note: Adjustment direction is opposite to beam movement.


  • Loosen the four screws of the expander holder.

  • To move the beam RIGHT: Slide the entire holder assembly LEFT.

  • To move the beam LEFT: Slide the entire holder assembly RIGHT.

Vertical (Y-Axis) Adjustment


  • Loosen the three screws of the expander holder.

  • To move the beam DOWN: Slide the holder assembly UP.

  • To move the beam UP: Slide the holder assembly DOWN.

Repeat adjustments until the beam is perfectly centered.

Then tighten all mounting screws securely.
