6.2.6 Cleaning
• Use a blower or a lens brush to remove dust on the lens or the optical filter.
• Do not disassemble front flange.

• Do not use benzene, thinner, alcohol, liquid cleaner or spray-type cleaner.
6.2.7 Adjusting the C-mount (mvBlueFOX3-2xxx-1xxx)
The mvBlueFOX3-2xxx-1xxx does not support back focus adjustment. However, with the four screw locks at the
front of the lens holder, it is possible to rotate the C-mount ring.
Warning
In combination with mvBlueFOX3-2089 and mvBlueFOX3-2124 the C-mount lens holder has to look upwards
during the adjusting. Otherwise the aperture can jump out of the guide.
• Loosen the screw locks with an Allen key (2.5 mm).
• With it, you can adjust the position of the lens, for example, to have the scale or the locking screws of the lens
at a specific position.

Always tighten the screws in a diagonal sequence first slightly and then little by little to a torque of 0.9 Nm.
