Warranty and Maintenance
The Cobolt lasers should not be opened for any reason. The warranty will be void if any of the system units are opened.
All laser parameters are set at the factory, and there are no adjustments required (other than those described in this
manual for operating in different modulation modes and at different power levels).
Cobolt provides a system warranty of 24 months after delivery with unlimited hours of operation on wavelength 375
nm
–
561 nm and a 24 month or 5000 hour limited warranty on wavelengths > 600 nm. The laser systems are designed
for modular replacement or repair if the laser head or key control box malfunctions. The fiber pigtailed option has a
12-month limited warranty on fiber related workmanship. The warranty is invalid if the laser system is operated
outside of the specific limits and conditions as outlined in this document.
Service
Due to accuracy tolerances, calibration differences and allowed power drift there may be discrepancies between the
Cobolt measurement of the optical output power and the customer measurement equipment. If the output power
deviates from the reported value please contact your local Cobolt representative for an online re-calibration.
If the laser does not function, do not attempt to open any of the units, or the warranty will be voided. Call or e-mail
your local Cobolt representative for consultancy and to request an RMA number (see back cover for contact
information). If an RMA number is issued and the laser needs to be shipped back to Cobolt or your local representative,
please pack the complete system for shipment using the original package or equivalent. Ensure the unit is free from
thermal paste before packing. The warranty covers repair or replacing the unit at the option of Cobolt.
