SCENARIO III : SMALL SIZED COLOR FILTER WHEEL
The small sized camera can be fitted with either smaller sized or medium sized color filter wheel (CFW). Please
choose one that is suitable for your system. CFW 2 and CFW 3 share the same connection method, in the following
demo, only CFW3 is shown.
The CFW can be threaded directly onto the camera without any extra adapters as shown per follow. Attention: the
CFW adapter does not add back focus length because the design is to let the top of cam (020085) plug into CFW,
the total length is 8mm still.
Alternatively, adapter 020063 can replace the original adapter in the original imaging chain. There are 2 major
advantage of such replacement. Firstly, it consumed less back focus. Secondly screws are used in fixing the CFW in
place, by which may reduce tiltness in the imaging chain. Such method requires minor works by opening the CFW
and removing the original adapter. Detail illustration can be found in the appendix.
