6.5.2 Manual Position and Focus Controls
Precision X-axis positioning is by rotating a knurled hand wheel with a hand crank, as shown in the following figure. The stage can be disengaged from the shaft of the hand wheel by raising the lever of a latch block around the shaft, thereby allowing the stage to be pushed directly by hand for coarse X-axis positioning. The stage is reengaged to the shaft by lowering the lever of the latch block.
Y-axis positioning is through the large hand crank at the base of the unit, as shown in the following figure. Rotate clockwise to raise the stage, counterclockwise to lower the stage.
Focus adjustment over 1.97 inches (50 millimeters) is achieved by moving the stage horizontally toward or away from the camera optics. This adjustment uses a hand wheel with a hand crank at the front of the stage, as shown in the following figure. Rotate clockwise to decrease the distance to the optics, counterclockwise to increase the distance.
