Maintenance and Cleaning
The Exicor 150AT requires very little maintenance.
System Performance Check
Exicor systems are delivered with a sample optic that can be used for system
performance checks. The user should periodically measure this sample to make
sure the system is still working properly. Follow these steps to measure the sample:
1. Mount the sample on the X-Y stage. Rotate the sample so that the fast axis
is at roughly 22°. The fast axis of the sample should be marked by lines on
the top of the holder. Or in the case of a polymer film sample, the fast axis is
always along the short dimension of the polymer (refer to the figure below).

2. Let the sample sit for at least 10 minutes. This ensures that the temperature
of the sample has become steady after handling.
3. Perform a stationary scan of 100 points at the center of the sample. Be sure
to take air offsets before this scan.
Compare the mean and standard deviation to the data provided by Hinds
Instruments for this sample. Some variation in the mean is expected due small
changes in temperature and humidity. The standard deviation should still be within
the acceptable range (see the ATP document for the proper range). Also make sure
that the fast axis is being reported correctly.
Determine the appropriate system check schedule that fits well with the system use
schedule. A system check should be performed at least once per week but is
recommended before every shift.
