Important!
•
Materials used in the external cooling circuit must be chosen to avoid corrosion. Never use
aluminium, zinc, mild steel or cast iron components. Suitable materials are stainless steel,
copper, copper alloys and opaque plastics. Only use pipework that is impervious to light in
order to reduce the possibility of bacterial contamination of the cooling system.
• The coolant temperature must be kept above the dew point in order to prevent formation of
condensation on internal laser components.
•
Completely drain the cooling system before shipment or storage.
6.2.4. Beam delivery optics purge gas
If the internal or external beam delivery is contaminated with fume, water vapour or debris then these
contaminants can absorb the laser energy and cause laser power fluctuations and steering of the laser
beam. In severe cases, laser optics can be contaminated and damaged.
The laser internal beam delivery is fitted with an optics purge system using contaminant-free
compressed air or nitrogen.
A non-return check valve is fitted to the internal beam delivery. The check valve opens and allows the
excess purge pressure to escape.
Once the purge pressure has dropped to the correct pressure, the valve will close automatically,
preventing dust, moisture and contaminants from entering the optical system.
6.2.5. Electrical power connections
The laser requires a 50V DC power supply, either supplied locally or available from Luxinar. For
specifications refer to section
.
The connecting cable cross-section depends on the laser model and cable length. Refer to the following
table for cable selection.
