PDB440x and PDB450x detectors
4 Maintenance and Service
Protect the PDB440x and PDB450x detectors from adverse weather conditions. The PDB440x
and PDB450x detectors is not water resistant.
Attention
Be very careful when connecting the fibers to the optical inputs! The photodiodes are
mounted such that the gap between the protective diode glass and the fiber tip is as
small as possible. For this reason, be careful not to tighten the fiber connector too much
in order to avoid damages to the glass window that protects the photodiode.
Attention
To avoid damage to the instrument, do not expose it to spray, liquids or solvents!
The unit does not need a regular maintenance by the user. It does not contain any modules
and/or components that could be repaired by the user himself. If a malfunction occurs, please
contact
Thorlabs for return instructions.
Do not remove covers!
To clean the PDB440x and PDB450x detectors series housing, use a mild detergent and damp
cloth. Do not soak the unit in water or use solvent based cleaners.
When cleaning the windows of the photodetectors, please remember that is a sensitive optical
device. Gently blow off any debris using compressed air and wipe gently with an optic tissue
wetted with isopropanol or alcohol.
