Adjustment of C-Mount

PIKE cameras allow the precise adjustment of the back focus of the C-Mount

by means of a back focus ring which is threaded into the C-Mount and held

by two screws on either side of the camera. The mechanical adjustment of

the imaging device is important in order to achieve a perfect alignment with

the focal point of the lens.

Individual adjustment may be required:

• if you cannot focus correctly at near or far distances or

• if the back focal plane of your lens does not conform to the C-Mount

back-focus specification or

• if you have e.g. removed the IR cut filter.

Do the following:

1. Loosen screws (location as shown above by arrow) with an Allen key

(1.3 x 50; Order#: K 9020411).

2. With the lens set to infinity or a known focus distance, set the camera

to view an object located at 'infinity' or the known distance.

3. Rotate the C-Mount ring and lens forward or backwards on its thread

until the object is in sharp focus. Be careful that the lens remains

seated in the C-Mount.

4. Once focus is achieved, tighten the two locking screws without applying

excessive torque.
