3.3 Focussing the Camera on the Aperture
If the Optosplit II aperture is not in sharp focus, then adjust the fine
focus on the camera as follows:
1.
Set an aperture size of less than half the width of the
camera frame.
2.
Slacken the two hex screws that retain the output
rotating ring to allow the camera to rotate.
3.
Separate the two images slightly with the Split control.
4.
Slightly loosen the hex screws on the focussing ring.
Adjust the focus whilst ensuring the optosplit is
secure, and holding the camera, until the apertures
edges are in sharp focus.
5.
Then lock off the focussing ring by re-tightening the
hex screws. Ensure the camera is again lined up with
its top orientated the same way as the top of the
Optosplit II and then lock off the output rotating ring.
6.
Tighten the two hex screws that lock the camera
rotating ring.
