How it Works
With the Dual Head installed, the special “Beam Splitter” optic inside of the Dual Head splits the laser
beam in half. It reflects one half of the laser beam’s energy down through the focus lens inside the Dual
Head and passes the other half of the laser beams power through the beam splitter. The laser beam
goes through the beam tube and then onward through to the single heads #3 mirror where the laser beam
is reflected downward through the single head’s focus lens.

By splitting the laser beam’s power in half, you effectively get approximately 50% of the power at the Dual
Head and 50% at the single head. However, since the beam splitter absorbs some energy, and there are
other losses involved, getting an exact 50/50 split is not possible, but the difference in most applications,
is negligible.
Installation
NOTE: The example below assumes that you have also purchased the Air Assist option. If you do not
have the Air Assists option, please ignore any references to the “cone(s)” or “air hose” as these two items
are the only differences between the regular Dual Head and the Dual Head with Air Assist option.
• If your laser system is not off right now, turn it OFF.
• The Dual Head will be installed to
the left side of the single head.
Pick up the Dual Head assembly and
note that the lower X-axis bearing
pivot arm should be in about the 10
o’clock position (A) (from the
backside view, and 2 o’clock from
the front side.) Starting with the
Dual Head rotated about 30-45
degrees clockwise and tilted back
towards you, slightly position the
lower X-axis bearing in the lower
bearing track of the X-axis rail.
Gently pull up on the Dual Head while
turning it counter-clockwise back to the 0 degree position and “hooking” the top two X-axis bearings
into the upper bearing track of the X-axis rail.
• Verify that all three bearings are in their respective track. Gently push the carriage to the left and
then back to the right. It should roll smoothly, if not, verify and/or re-install the Dual Head.
NOTE: B in the above image shows the Air Assist version.
