the sensor surface, otherwise liquid gas drops may hit the sensor and leaving marks
visible in the camera image!
Attention
The camera sensor cannot be cleaned by conventional methods using
ethanol or cleaning tissue! Warranty will be violated when other cleaning
methods are used.
Keep a distance of minimum 4 inches (10 cm) when cleaning using
compressed gas.
In case a professional cleaning of the windowless CCD sensor is required, please
return the instrument to Thorlabs, see the appropriate Addresses .
ND Filters
ND filters (see Filter Wheel )can be cleaned by conventional methods using pure
ethanol and/or cleaning tissue. You may clean the front surface of the ND filters
without unscrewing the appropriate filter holder. After tissue cleaning it is
recommended to remove remaining lints using compressed air.
In case dust is still visible within the camera image, unscrew the filter holder and
clean the ND filter's rear surface. In addition, remove dust from the sensor itself
(compressed air only!).
The instrument itself may be cleaned using a wet lint-free cloth.
