Bonito PRO Technical Manual V1.0.0
Planarity adjustable mounts
Bonito PRO cameras allow planarity adjustment of the mount relative to the
camera sensor. Adjustment can be made for overall flange focal distance (Z
distance), and planarity (Z-tilt). The following steps describe Z adjustment using a
standard lens and a target. However, measurement tools such as an optical depth
micrometer could also be used.
1.
Using a compatible lens, set the lens to infinity and image on a target (10 to 15
m). Target should highlight focus levels at center image and at the corners of
the image. A lens with a long focal length, or adjustable zoom lens, allows
more precision for this operation and reduce the overall size of your target.
2.
Use a 1.5 mm hex ball head driver to loosen the screws.
Adjust the three tilt adjustment screws, until all targets are in focus.
3.
Tighten the three screws and recheck the focus.
NOTICE
Modifying the factory default adjustment is under the responsibility of the user.
Exercise caution when modifying the planarity adjustment. Use a 1.5 mm hex ball
driver to loosen the three spring loaded screws, adjust the tilt adjustment screws
as required, then secure the screws.
