Setting the Camera Tube Mounting Position
1. Rotate the Focus Adjust, so that it is in the center of its travel.
2. Hold the Camera Tube and loosen the Allen Screw on the right side of the
Camera Tube Mounting Block (next to the Thumb Screw).
3. With the system and Monitor ON, slide the Tube Assembly up/down until the
sample below is in focus.
4. Once the sample is in focus, tighten the Allen screw.
5. Perform the Optical Center and Follow Focus Setup procedure below.
Optical Center and Follow Focus Setup
Follow Focus
1. Place a sample in the holder.
2. Zoom all the way in and focus on a die.
3. Zoom all the way out. If it is still in focus, STOP. If not, go to step 4.
4. Loosen the (3) Focus Screws on the camera, and (1) of the Optical Center Screws
(OCS).
5. Turn the Center Collar until it is in focus.
6. Tighten all screws.
7. Repeat steps 2 thru 6 until focus is good.
Optical Center
1. Align the two cross hairs in the center of the screen.
2. With the Camera zoomed all the way in, move a corner of a die (or other easily
recognizable spot) to the center of the cross hairs.
3. Zoom out. If the spot is still aligned with the cross hairs STOP! If the spot has
moved go on to step 4.
4. If the spot has moved, use the (3) Optical Center Screws (OCS) on the Camera
Tube to move the spot back to the center of the cross hairs.
5. Zoom all the way in and line up a spot with the cross hairs. Zoom out.
6. It should be close at this point, but usually requires steps 2-5 to be repeated
twice. This is a critical alignment to insure proper picking.
