CX41 Parts and functions

Coarse focus knob – M

The coarse focus knob should be used with caution! Turn it very slowly to bring the specimen into near perfect focus. You don't want to turn this knob too quickly and have the objective crash through the specimen damaging the slide and the objective! You should only have to use the coarse focus once with each specimen. When you change to a higher objective the specimen will be almost in focus and the only adjustment will be with the Fine focus knob (N).
