Figure C
7-2-1. Focus control input
With the voltage to input to the B terminal, the focus is changes. As for the relation between the focus control
voltage and the focus, it is as shown in the following.

NOTE:
The control voltage and the
focus, which are shown below
are a reference value. Because
there is a little difference, see
as the reference data.
