Spectral Response

The spectral response curve excludes lens characteristics and light source
characteristics.
To obtain best performance regarding the camera’s blooming, smearing and dark
signal non-uniformity characteristics, use of a dielectric IR cut-off filter is
recommended. The filter should transmit in a range of 400 nm to 700...720 nm, and
it should cut off from 700...720 nm to 1100 nm.
A suitable filter is included in the C-mount adapter.
The F-mount adapter does not include the filter. A suitable filter type is the B+W486,
for example.
Caution!
A102
k
cameras shipped with a C-mount lens adapter are equipped with an IR cut
filter as standard equipment. The filter is mounted in the lens adapter. The loca-
tion of the filter limits the thread length of the lens that can be used on the cam-
era. The thread length on your lens must be less than 7.5 mm. If a lens with a
longer thread length is used, the camera will be damaged and will no longer op-
erate. See Section
5.5 for more details.
Cameras without an IR cut filter in the C-mount lens adapter are available on re-
quest.
