7 Filter Wheel

The X-Series cameras have a 4-position, motorized, warm filter wheel. The wheel sits between the
lens and the detector warm window. The filter wheel can be seen by removing the lens as shown in
the picture below.
The filter wheel can be controlled from the camera controller [Sec. 5.4.2.4.2]. The filters are held in a
removable holder (shown below). Each holder can hold one filter up to 2mm thick, or two filters with a
combined thickness of 2mm.
The camera keeps track of what filters are in the wheel by sensing a
set of magnets installed in the holder. The camera scans the wheel on
boot up (or on demand). The filter page in the camera controller
displays the detected filter IDs. If a factory calibration range is
selected that requires a filter, the camera will automatically search the
wheel for that filter and put it in the field of view.
In most cases the filter wheel will be populated at the factory. If a user
has more filters than can fit in the wheel at one time, it is easy to swap
a filter. To do this you will need the filter wrench that is included in the
shipping case with each camera. It looks like the picture to the right.
To remove a filter, first remove the camera lens, so you can see the
filter wheel. Then, go to the Setup>>Filter/Flag page in the controller and press the "C" button next to
the filter you wish to change. The camera will put this filter in front of the detector, where it can be
seen. Each filter holder has two holes (located between filter ID slots 1&2 and 4&5, at the 3 o'clock
and 9'oclock positions when installed). Insert the two pins on the wrench into these holes. Twist
gently a few degrees counter-clockwise and you will feel the holder click free of the retention springs.
