The Filter Wheel Assembly is only compatibile with Collimators that use Optek optical sensors. Before
you change the Filter Wheel Assembly, you must determine if you also need to change the Collimator so
that it is compatible with the new Filter Wheel Assembly.
Locate the Collimator Box Number given on the label on the side of the Collimator. Use the Collimator
Box Number in the table below of the Collimator to identify the type of optical sensors that are used by
the current Collimator. Perform the task described in the table below depending on the Collimator Box
