To obtain the best performance regarding the camera’s blooming, smearing and dark
signal non-uniformity characteristics, use of a dielectric IR cut-off filter is strongly rec-
ommended. The filter should transmit in a range from 400 nm to 700 ... 720 nm and
it should cut off from 700 ... 720 nm to 1100 nm.
The camera’s F-mount adapter does not include an IR cut-off filter. A suitable filter
type is the B+W486, for example.
Using a filter with a higher cut-off point than 700 ... 720 nm will increase the camera’s
response, but keep in mind that the response increase will occur because the camera
is reacting to IR light, not visible light.
