8.2 Contrast Methods
All of the contrast methods of the Leica
DMI4000 B and Leica DMI6000 B can be
selected and controlled via the variable function
buttons and the Leica Application Suite (LAS).
The only exceptions are methods that involve
components requiring manual control (e.g.
systems with manual analyzers). The following
section describes the use of the function
buttons on the stand. For instructions on the use
of the software, please refer to the separate
manual.
Contrast methods for the Leica DMI3000 B are
controlled via the manual condenser, the
manual objective turret, as well as turning
knobs and sliders at the microscope.
