Mounting the Laser Head

The cylindrical construction of the laser head allows for easy mounting in ring clamps, V-blocks, or similar
mounting hardware without affecting the laser's alignment. Use caution when clamping onto the laser, as too
much pressure can damage the aluminum housing or cause misalignment. The front bezel has four 4-40 UNC
holes to secure standard HeNe optional accessories. The laser head should always be secured in place and not
allowed to move freely. Not only can the laser roll off the work surface and break, but the laser emission can be a
health hazard.
See the table below for the recommended number of
mounting points. It is recommended to use V-block
mounts (see figure to the right). Thorlabs offers fixed
and kinematic mounts.

Assembly

It is suggested that the HeNe Laser Quick Start Guide (a separate document found enclosed with the laser) be
used to assemble the laser system. Listed below are the steps needed to assemble the laser system.
This laser system includes a fixed-voltage power supply that is factor-set for either 120 (no dash), 230 (-EC), or
100 VAC (-JP) operation. The laser must be purchased correctly configured for the appropriate regional current.
The proper mains voltage cord must also be used.
Never remove the Alden plug from the power supply while the power supply is plugged into the
mains. Doing so may result in arcing that could damage the laser head or power supply.
1) Make sure the laser head is secured to your work surface and pointed safely away from people and
directed into a beam block, beam dump or similar nonreflective surface.
2) Plug the high-voltage cable from the laser into the rear of the power supply. Confirm that the Alden plug is
well-seated. The first few times the plug is inserted, it may require more force than expected. Failure to
plug the connector all the way in can result in the laser failing to lase or arcing and damage to the power
supply or laser head.
3) Insert the shorting remote interlock connector into the back of the power supply. Note that the plug only
goes in one way. Also note that the LED light on the front of the power supply will light even if the
interlock is not inserted.
4) Plug the AC connector into the mains outlet.
5) Insert the key into the front panel of the power supply.
