IRRORS
The two flipper mirrors can be flipped up or down to select the desired path of the beam
leaving the reflection tower. The beam can be directed to the CCD camera, the PMT, or to
optional hardware.
Coarse adjustment of each mirror is performed by loosening the screw underneath the sup-
porting column. Use the yoke supplied with the Aurora-2 to hold the mirror temporarily in
place while the position is adjusted. Once the position is set, tighten the screw under the
base of the column.
The X and Y fine-adjust screws are on the mount.

IRROR
The rotating mirror is controlled by a knob on the front of the stage, as shown in
Figure 2-20. The knob has two positions: the counter-clockwise limit selects the reflection
objective; the clockwise limit selects the transmission objective.
