8 Mechanical Considerations
8.2 Adjusting the Back Focus
The back focus of your Photonfocus camera is correctly adjusted in the production of the
camera.
This section describes the procedure to adjust the back focus if you require that because e.g.
you are using a special lens.
1.
Screw a lens strongly into the camera's C-mount ring.
2.
Unscrew the 3 small screws that lock the C-mount ring with a hex-wrench of size 0.89 mm.
The position of the screws is shown in Fig. 8.2. The ring can now be screwn upwards or
downwards by turning the lens.
3.
To adjust the back focus fully open the aperture of the lens and set the focus to infinite.
4.
Start the image acquisition and point the camera to a straight edge/line in a distance x (x
= infinite distance of your lens) from the camera, e.g. a door frame.
5.
Screw the ring upwards or downwards until the straight edge/line (distance: infinite) is
also straight on the camera image.
6.
Tighten the small screws. As the ring is locked, the lens can now be easily removed.
