Maximum Allowed Lens Thread Length

The C-mount lens adapter and the CS-mount lens adapter on all cameras (mono and color) is
normally equipped with a plastic filter holder. The length of the threads on any lens you use with the
cameras depends on the lens adapter type you use with the camera:
Camera with C-mount lens adapter (see Figure 21):

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 lens adapter (see Figure 22):

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.
NOTICE
If either of these 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 will be populated with an IR cut filter. On monochrome
cameras, the filter holder will be present, but will not be populated with an IR cut filter.
You can obtain lenses with correct lengths of threads from Basler (see www.baslerweb.com).
