SECTION 6: MAINTENANCE
DO NOT TRY TO OPEN THE MECHELLE SPECTROGRAPH. IF YOU OPEN IT, THE WARRANTY WILL BE VOID.
Maintenance of the Mechelle spectrograph is minimal. There are no user-serviceable parts inside the spectrograph. The
optics in the Mechelle spectrograph are factory adjusted before delivery. Inside the Mechelle spectrograph there are
sensitive parts that must be handled by authorised personnel only in a dust free, clean environment. Please observe the
following general precautions:
•
When the Mechelle is not being used, it is recommended to protect the fibre optic input connection with the
protection cap, included in the delivery
•
Never use aggressive cleaning substances, e.g. benzene, spirit, nitro solvents, etc. commonly found in labs.
Such substances may destroy or damage the surface on which they are applied
•
During use, the Mechelle should be protected from hard shocks or strong vibrations
•
The Mechelle should be protected from high humidity levels and temperature changes
•
It is important not to scratch the surface of the fibre ends, as this significantly will reduce the light input. It is
therefore recommended to always keep the protection cap on each end of the fibre when it is not in use. The
fibre itself should be cleaned only by dry dust free air or adequate fluids for optical surfaces
