1. Unscrew 14 silver bolts that hold down the top cover
– they are spring loaded and will pop-up once loose.
2. Slowly remove the cover –
detach the GND wire
that
is attached to the top cover from the inside of the
system! To detach the wire gently pull it out from the
connector.
3. Removal of the cover will show the two internal
defeatable magnetic interlocks. You must flip over the
right side of the magnetic interlock until it touches the
other side. You will be able to read the warning label
“Interlock Defeated”.
4. Power up the system as normal.
5. Create a red beam effect (point) and check visually
whether the red beam hits the exact centre of the
bottom scanning mirror. If not, use dichroic mounts DF5
to adjust the beam path accordingly (diagram below).
To adjust the dichroic mount use the two adjustment
knobs – each works for one axis.
6. Create a cyan beam effect (point) and check visually
whether the green beam hits the exact centre of the
blue beam at the dichroic filter DF2. If not, use dichroic
mounts DF1 to adjust the beam path accordingly.
To adjust the dichroic mount use the two adjustment
knobs – each works for one axis.
7. Create a full size cyan circle (static tunnel effect) and
check whether the green circle overlays the blue circle
in all points around the shape. If not, use dichroic mount
DF2 to adjust the beam path accordingly. To adjust the
dichroic mount use the two adjustment knobs – each
works for one axis.
8. Create a full size yellow circle (static tunnel effect) and
check whether the green circle overlays the red circle
in all points around the shape. If not, use dichroic mount
DF3 and/or DF4 to adjust the beam path accordingly.
To adjust the dichroic mount use the two adjustment
knobs – each works for one axis.

Although KVANT uses the latest
technology to protect all the critical
components inside this laser system
against Electrostatic Discharge, the
semiconductor laser diodes within
this system are extremely vulnerable
to it. This is due to some of the
electronic components being exposed
when the top cover is taken off.
If you decide to proceed with the
Beam Alignment process yourself,
it is absolutely essential that all the
common ESD protection rules are
strictly followed. We don’t accept
any responsibility for Electrostatic
Discharge damages to laser diodes
caused by customer.

In the defeated position the label
“INTERLOCK DEFEATED” becomes
visible as shown in the image. Placing
the magnetic interlock in the defeated
position raises the interlock higher than
the edge of the housing which will not
allow the cover to be installed.
