Filter exchange for C-mount device

By default, an infrared filter is mounted between the camera chip and lens in the C-mount
device. If necessary, this can be replaced with a daylight blocking filter (part no. 50117985,
see chapter 9.3) for applications that work with infrared light.
Attention!
Only replace the filter in an environment that is very clean, dry and dust-free. It is best to
wipe off the replacement filter with a clean microfiber cloth before inserting the filter. Use
suitable gloves when doing this!
