Back Focus Adjustment
The back focus adjustment is located at the front of the camera and is accessible from either side of the case.
To adjust the back focus:
1. Loosen the two back focus locking screws (one on each side).
2. Turn the back focus ring counterclockwise until the CCD sensor assembly is as far away from the back of
the lens as possible.
3. Turn the back focus ring clockwise until focus is achieved.
4. When the back focus adjustment is satisfactory, tighten the locking screws. Do not over-turn or force the
back focus adjustment ring.
NOTE: Always turn the back focus ring such that during focussing, the CCD sensor assembly is brought
towards the back of the lens (that is, clockwise). If the point of best-focus is passed, repeat the back focus
procedure from step 2.
