filter holder. The length of the threads on any lens you use with the cameras depends on the lens
mount:
Camera with C-mount (see

The thread length can be a maximum of 9.6 mm, and the lens can intrude into the camera body
a maximum of 10.8 mm.
Camera with CS-mount (see

The thread length can be a maximum of 4.6 mm, and the lens can intrude into the camera body
a maximum of 5.8 mm.
If either of the above limits is exceeded, the lens mount or the filter holder will be damaged or
destroyed and the camera will no longer operate properly.
Note that on color cameras, the filter holder is populated with an IR cut filter. On monochrome
cameras, the filter holder is present, but is not populated with an IR cut filter.
You can obtain lenses with correct thread lengths from Basler (see www.baslerweb.com).
