Note: Make sure that the unused leads are not touching and that there is no possibility that the leads could
short due to exposed wires.
2.2.3 Attaching the Camera Lens
The RM-67X camera accepts 1/3” or larger format size C-mount lenses. To attach the C-mount lens to the camera, carefully
engage the threads and rotate the lens clockwise until it firmly seats on the mounting ring. Do not force the lens if it does
not seat properly. Please note that some lenses with extremely long flangebacks may exceed the mounting depth of the
camera.
2.2.4 Adjustable Back-Focus
Before cameras are shipped, back focus is carefully set using a collimator, oscilloscope and other specialized equipment.
While the factory-set focus serves well in most cases, an adjustable back focus makes it possible to improve image
sharpness when using lower-cost zoom lenses, custom optics, or in unusual parameters.
There should be an obvious need to refocus the lens before attempting to change the back focus. This is an exacting task.
Some cameras have been returned to the factory to reset the back focus after failed attempts to change the focus by
customers. It is wise to label cameras whose back focus was adjusted.
1. The camera must be connected to a monitor before attempting to adjust the back focus.
2. To back focus the camera, first attach a C-mount lens in the mount. Be certain that the lens is properly
seated.
3. Next set the lens focus to infinity (if the lens is a manual iris, set the iris to a high f number while still
retaining a well illuminated image).
4. Loosen the three miniature hex set-screws (use a 0.9 mm hex wrench) that lock the focus ring in place.
Slowly turn the lens and focus ring assembly back and forth until you obtain the best image of the desired
object. This sets the back focus. Once the best image is obtained, tighten the focus ring set-screws until
they are snug. Do not over-tighten the screws.
Note: Mini-bayonet cameras adapted to C-mount do not have the back focus feature.
