Notes:
1.2 Data at 25°C cooling water temperature. [IS45 Red and all other wavelengths]
2. Reduced lifetime if used above nominal operating conditions.
3. Others available upon request.
4. A non-condensing environment is required for storage and operation below the ambient dew point.
5. It is essential for the module to work correctly that 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.
