The system will be installed at the customer facilities and its performance
demonstrated as per ordered specifications by the manufacturer.
A list of spare components that may be required over a period of two years can
be quoted separately.
Diagnostic devices and any other optional devices applicable for the systems be
be quoted separately.
A user manual containing technical details such as optical layouts, circuit
diagrams, component details and operations/servicing instructions should be
supplied with the system.
Warranty: Warranty on each subsystem (seed laser, pump lasers and electronic
components), and the system as a whole is 1 year and 90 days warranty for the
optical components. In case of any failure/malfunctioning during the warranty
period, the system/ sub-system should be replaced / repaired free of charge.
