3
Reduce lifetime if used above nominal operating conditions.
4
A non-condensing environment is required for storage and operation below the ambient dew point.
5
It’s essential for correct functioning of the module the cooling water temperature and flow rate are monitored as an interlock for
interrupting the laser current immediately if a value exceeds or falls below the given parameter.
