Focusing

Focusing raises or lowers the stereomicroscope using the focusing drive. The specimen detail is brought into sharp focus as soon as it is in the focal point of the objective.

ρρ The focusing drive can be operated either left- or right-handed.

Focusing

ρρ The inner, coarse adjustment is used for covering great distances.

ρρ The outer, fine adjustment is used for fine focusing.

Coarse/fine adjustment

The sharpness is adjusted using the coarse/fine adjustment. The resolution of the coarse/fine adjustment is 1 µm.

•2. The coarse/fine adjustment carries a load of up to 15 kg.
