Removable IR Cut Filter
In case of 1CCD camera, light will be 
separated to RGB signals by on-chip filter 
on the CCD. One pixel consists of R x 1, B x 
1, G x 2.
Therefore, this filter cannot be removed 
and the sensitivity of R channel is one 
fourth.
In case of 3CCD, light will be separated to 
RGB signals by prism and the CCD consists 
of monochrome. In order to cut IR(Infra 
Red) light, the filter is implemented before 
the prism. This is so-called “IR cut filter”.
This “IR cut filter” on the KY-F550 can be 
removed and changed to the dummy filter 
consisting of transparent glass. As a result, 
the sensitivity at the range of IR will be 
dramatically increased. This picture is 
monochrome.
