A2.2 CHANGE FROM F-MOUNT TO C-MOUNT

Instructions on how to change the optical input from F-mount to C-

mount:

Step 1: Remove F-mount Adapter

Grasp the F-mount adapter at the black ring (counter ring) and turn

it counter clockwise.

Step 2: Insert C-mount Ring

Carefully screw the ring completely in and tighten the two Hexagon

socket screws.

Adjust Back Focal Length

First of all, attach a lens to your C-mount adapter. Then set the focus

of your lens to infinity. After that, look for an object in infinity* and

generate a sharp image by turning the smaller ring of the adapter.

Then fix this position with the two small indented screws.

*rule of thumb: object should be away about 2000 times the focal length in mm

Limitations of C-mount lenses

Keep in mind that c-mount lenses could

cause shadings at the edges of big sized

sensors. Most c-mount lenses are able

to illuminate a maximum image circle of

11 mm (2/3”), 16 mm (1”) or 22 mm

(4/3”) diameter only. The pco.edge

cameras have a sensor diagonal from

18.8 to 21.8 mm, it follows that you have

to use the ROI function for a shade less image while using the c-

mount adapter with the two smaller C-mount diameters.
