Collimator
The spectrograph is focused by moving the collimating lens. The lens
is controlled remotely from the
Motor
Control software. The
nickelfocus or
nickelfocusp
program is a useful tool for focusing the spectrograph.
The collimator can be accessed via a panel on the west side of the
spectrograph. It should not be necessary for observers to ever access
or touch this lens.
