Chapter 4 Cleaning and Maintenance
Under normal operating conditions, the modulator needs very little, if any
maintenance.
4.1. Cleaning the Optics
The modulator crystal is recessed inside the housing and under normal
conditions, the crystal faces should not need cleaning. If necessary, use a gentle
stream of compressed air (dry nitrogen under low pressure or a can of
compressed air made specifically for cleaning optics).
WARNING
Damage may result from excessive cleaning air pressure or if condensation is
allowed to build up from using a stream of compressed air from an inverted
can.
4.2. Cleaning the Modulator Housing
The housing can be wiped clean with a lint free rag wetted with propanol or a
commercial window cleaner. Do not soak the housing
– it is not watertight and
any moisture introduced inside the modulator may cause condensation problems.
